r* said about a whole new storyline, wich makes me think it shoud be new characters. if not, then all the previous games had "whole new storylines", so why mentioning that to vcs?
i bet vcs will be a greater game for psp, and i say that not because i am a fan, but because lcs came with new aditions compared to the old liberty, like scooter shooter, photo opps, salesman, random enemies like ma's killers and all. same way, vcs will boost the gameplay forward, not that will have the same things "plus 10%" (that's not r* style, remember?), maybe will have it's own little side missions, all new and crazy and exclusive(scooter shooter is a killer, just imagine yourself driven by an old happy gramma on a cute little scooter to blow up all those mad and fast and dangerous criminals, ot's illarious
speaking about exclusive content from a game to another, i think this gives a unique style to each of them. if all cityes woud have tunels they woud be a little bit the same somehow. and if all of them had the same side missions...
ok, on the finally: don't know who is on the cover, but rubina seems possible. as for the gameplay possibilities, in my opinion swiming won't be available, don't know about crouching and i am damn curious what r* will invent to keep the bridges blocked this time
