From my experience, two gaming consoles are more than I can manage. I can hardly keep up with my PS3 games, with more than 10 titles from my Wii on backburner. Now add dozen of DS games and couple more on PSP...
If I were you I'd count the trully exclusive titles on Xbox and if there is a way to play them on PC, if you own decent PC, you can play most multiplatform games without any problems (mine is 4 years old and I can run ME2 at max settings). Also main strenght of Xbox is it's online service, without paying for the gold membership, does it offer enough? This was my thinking when I was deciding whether or not to buy an Xbox.
MY HYPE LIST: 1) Gran Turismo 5; 2) Civilization V; 3) Starcraft II; 4) The Last Guardian; 5) Metal Gear Solid: Rising
