For me there is something wrong with the Xbox360 line-up:
game like Mass Effect or Bioshock (the 2 games will receive 9/10 from reviewer I think) are too much PC targeted.
I m not sure it will move average console player.
I think Halo3 / GTA4 can do it better.
I think game like HeavenlySword / Unchartred / Ratchet are REALLY more console targeted even if "hardcore gamer" will prefer ME/BS.
For me the big point on Sony to counter Microsoft :
- big price cut to make people buy their console as quick as possible
- big announcement for 2008 to make PS2 owner wait and NOT buy Xbox360 :
"I have 350$, I want to buy a console to play GTA4 or PES2008, the only console that I can buy to play these games : Xbox360, I buy it so !!!"
If Sony succeed to keep the focus on their exclusivity coming in 2008, people may think :
"hey I will wait to buy a PS3 when she will be cheaper, no Xbox360 for me"
Time to Work !
