This may have been asked/answered already and if so I apologize. Has there been any hint as to whether the stats on vehicles and guns will change drastically? I'm thinking the answer to this may go against the NDA but I'm asking nonetheless.

Given that both game mechanics for vehicles and combat got a heavy working over, basically a rewrite, the odds of the old numbers being applicable is very remote. I'm guessing the only thing they'd be good for is for benchmark comparisons when converting custom SR3 equipment or equipment found in the SR4 extra books before they come out.

thats kinda what I was guessing but I wasn't sure if there had been any rumors from the cons.

It was either the Origins thread or the Origins seminar that covered the new weapon damage codes. They are substantially changed.
