if money is not a problem, then i would go for the PS3.

the console is way better than the xbox360 in hardware terms and offcourse the blue-ray player.

the wii could be a choice if you like crazy fun games and value fun gameplay over incredible graphics.

and for the RPG : oblivion and FFXIII are coming to the PS3!
and in the meantime you could play RPG's from the PS2 like roque galaxy, dragon quest and Final fantasy.
