They probably had to cut back on character animation and polygon counts to squeeze it into a current gen console.
It would be fine - if they were making a PC version alongside it. Really I don't want to buy any more 360 games, but I know that'll be the popular format for it for a while - If I want GTA5 it has to be on my 360, which will no doubt RROD the minute I sign up for another years live. I could get it for PS3, but my PS3 is living in the cupboard under the stairs (GT4 driving rig) - not ideal as GTA has always been a social game, the sort of thing that is quite fun just to watch. Damn you Rockstar, isn't the fact that the PC version of GTA4 is the only format still being played enough of an indicator!
The thing I'm most looking forward to are the bikes

- I want to take detours and explore, and the bike is the best vehicle for that, at least it was in SA. I like the sandbox elements they are bringing in, definitely seems that variety is the focus this time around - might even lead to some crazy DLC - The GTA4 DLC was brilliant, about as good as DLC gets - especially Lost and Damned IMO.

I got a fever, and the only prescription, is more memes.
