New bf game will just be the same with tanks that walk and guns that go peow instead of bang. It will probly still be conquest game mode, i hate that mode its boring lacks focus, why was rtcw and et so cool because of the neat objective system with a linear movement thru the level. Quake wars will be far better probly look better gfx wise to and feel better, 2 differnt teams not just reskinned will be very cool, objectives over scattered flags, and theres no EA involved
Also mod wise i dont think so important, as in full conversion while neat will not decide the popularity of the game, what mods for hl2 have come out? not alot, by the time they will newer games eclipse them. But its safe to assume IMO that et:qw will be better mod wise than bf2142 in all the mods for bf not one of them changes the game mode from awful conquest.
