While I'm fine with them coming to PC or Xbox, I don't think they need it.
I played some GoW on the PS2 and the first game was neat in a novel way, but grew bored of the game by the time the second one rolled around.
And never did get into Uncharted. Look at my past history and I don't mind on rails shooters (I actually like them!). But Uncharted is way too on rails for me without enough good gameplay to back it up. It's fine for people that want to watch a movie in the guise of a game, and I suppose it's good at that. Certainly not for me though.
It doesn't help that I think QTEs are the absolute worst thing ever introduced to gaming and both of those games feature extensive QTEs (at least GoW does, didn't play enough Uncharted to find out whether there's a lot or only a little bit).
The less games with QTEs on my gaming platform, the happier I am.
