With so little information about TimeSplitters 4 circulating around the Internet and Haze not going over well with a considerable number of people, it's hard to know what to expect from Free Radical.
Will TimeSplitters 4 be on par with TS2's level of excellence, or will it turn out more like TS3? There's really no telling at this point, but we do know that it may or may not contain nuns with chainsaws, which means the humor we've come to expect from the series will probably be present here.
In any case, Free Radical is currently running a poll asking which platform you want to play TimeSplitters 4 on. The PlayStation 3 is currently beating the Wii by a small amount, with the Xbox 360 and PC quite a ways behind.
I think it's safe to assume that TS4 appearing on PS3 is a given, considering Free Radical's experience gained from Haze. The real question here is whether or not it's worth porting to Wii, since the system is so unlike the other candidates.
