I think it important to note that the License for 3rd party 4e D&D stuff is so heinous that it might as well simply not exist. In the words of Admiral Akbar: "It's a Trap!"
It's
Here.The long and the short of it is that if you ever release anything under that license they have the right to take your IP, sue you for violating what s now "their" intellectual property, and force you to settle out of court with you paying their legal fees. And no, that's not hyperbole, that's seriously what it actually says. They can terminate your license at any time and you are still bound by the contract afterwards and they are not. Furthermore you can't ever publish anything OGL for 3rd edition D&D ever again if you print anything under the 4th edition license ever.
Basically no one is taking it. All the major 3rd party d20 companies are emphatically not jumping on board. Sword & Sorcery, Crafty Games, Paizo, etc. have all taken a giant step away and told WotC to stuff it. Even Necromancer Games, which had already started up a proposed 4e product line took a hard look at the GSL and shook their head in terror and disgust.

Interestingly enough, Red Brick Games announced yesterday that they have signed on as the first person to use the new GSL. They haven't stated whether or not they plan to adapt Earthdawn to it or not (I suspect not, myself), but... It'll be something to watch.
Chris Pramas at Green Ronin has said they will likely do some GSL stuff in the future, though they're wagons are still tied pretty heavily to both OGL/D20, with their Freeport, true 20, and Mutants & Masterminds stuff.
Sword & Sorcery is a bit of a surprise, but not by much. Outside of their licensed stuff (Warcraft, EQ. Which it's in their own interests not to switch systems for), I'm not even certain we'll see much, if anything from them.
No clue who Crafty Games are. Some Google, and... Ahh, Spycraft. Makes sense. DId they leave Alderac, or is this an imprint like SSS is for White Wolf? ANyways, again, no real surpise. Especially since I can;t see this working with a non-D&D setting.
Paizo's no real shock, after WotC cut them off. Honestly, the whole Pathfinder thing comes off as a tantrum on their part. WotC took their ball away, so now they're throwing a balled up rag around and refusing to go home

The thing is, many of these companies are pretty entrenched in what they're doing. The SSS stuff, especially Monet Cook's Malhavoc stuff, Ronin's True 20 and M&M, and SPycraft all diverged pretty heavily from standard D20, to the point where they bascially created a whole new game using the bare bones of the original. It's nice they showed that initiative, and riding the wave of lemming-like borg collective of D20 players helped give them their start, but I think with a bit of effort all of these could have been accomplished just as well, if not better, without the D20 logo and the OGL. Frankly, there's no way to adapt any of these to 4e without scrapping everything and starting from scratch. It's not in their best interests to do so in the least.
Paizo, meanwhile, it trying to pick up with WotC is leaving off with 3.5. I have my doubts as to how well they'll manage, personally. It'll be something to watch, but I suspect most D&D players that don't switch to 4e will either stick with the "classic" WotC material, or are already using Monte Cook's stuff or the True 20 stuff. At best they may pick up a book here or there as supllemental material.
I should note here as well that of the half dozen or so D&D groups I know of, the only one who allowed any non-WotC sourcebooks to be used was a group running Cook's stuff, and they were running the game using those as their primary books, and only allowed Malhavoc stuff, in additionto WotC material. I know some groups went nuts with the "Non-official" material, but I suspect they were pretty few and far between.
So honestly, I'd be surprised to see any of the big names in 3.X announce they were switching over. And frankly, I doubt WotC really cares. OUtside of the buzz that the D20 Zombie Attack caused, I don't think the D20 business really helped WotC at all, especially financially. The vast majority of the D20 stuff was utter crap and reflected poorly on D&D, and the stuff taht was decent went from D20 to OGL pretty fast and splintered off to the point where WotC's core books weren't needed, or weren't even compatible.
And it would be stupid for the OGL guys to drop their successful lines to try and work up something new from scratch for 4e. And yes, I agree, the GSL is kinda silly and very restrictive. But I think that's because WotC would like to actually get a piece of the action this time. And I can't really blame them too much.
As I keep saying, it'll be something to watch. It's a new development and a new direction for the hobby, and as always, the effects it has will be pretty far reaching.
