If it's only a console you're after, than look at the exclusive lineups. Personally here I'd have to go with Playstation 3, since there are more appealing games for me than on Xbox 360 and Wii. Few years back I'd have to point you to Xbox 360 for better RPG experience, but seeing as some of their titles are getting enhanced releases on the PS3, and with great exclusive titles such as Demon's Souls and White Knight Chronicles, it's on par now (maybe even slightly better). For racers, I sincerely believe Gran Turismo 5 will destroy all competetion and deliver the greatest racing experience of all times, so here you are settled :).
But also look for the expanded value, for me, PS3 is currently also dvd / blue ray / multimedia center. I believe that PS3 has the best value / price ratio of all the consoles.
MY HYPE LIST: 1) Gran Turismo 5; 2) Civilization V; 3) Starcraft II; 4) The Last Guardian; 5) Metal Gear Solid: Rising
