I guess would not mind a BF1942 remake with next gen graphics (not this gen)... outside of that though it would really need to bring something different to the table to get my interest.
TimeSplitters 4 is probably still happening though! I just read the latest news on wiki.
And I do prefer the WWII setting to the modern one, so I wouldn't mind seeing some WWII games appearing again. It's a shame some devs seem to follow the same settings in trend-like fashion. BF1943 was great and I'd love to see a sequel.
