A GM in need of Assistance!, The end of an Arc.. Or maybe it all. Options

[Belvidere]

I've been GMing SR4 for almost a year now and I think I'm an alright GM. But I've hit a bit of a roadblock with what I've got going on. I'm trying to come up with the end of the current arc my players are a part of, and possibly the current campaign.

As of right now, through a series or ridiculously complicated events which would take me far to long to explain the PCs have come into the possession of a dragon egg. And it's the egg of a great dragon to boot. (They're yet to find out whom it belongs to.) And they know Saeder-Krupp has shown significant interest in claiming the egg as theirs. A representative of SK has approached them offering half a million nuyen to each of them to hand the egg over no questions asked. They've only recently figured out it was the egg of a dragon. Calling upon contacts within the mob they got an informant to them and with a series of firefights that ended with a freighter exploding in the Seattle docks they've made a run to Vancouver and hiding out with their informant ("The Translator") who know mush more than she lets on.

Thats pretty much where we're at, they're on their way into Vancouver now... and I'm stumped as to what to do. Anyone have any cool ideas that they want to throw out in the open. It would be much appreciated.
