Sony wont make the same mistake twist, Sony PS4 will have so Many Launch titles that towards the end of PS3 (like 2012-2014) there be nothing but 3rd games as all of Sony's 1st party teams will be making Launch titles.
GT6 would be an Great launch title along with a Naughty Dog game, Sucker punch game, an big online title like MAG2 or Socom from Zipper Interactive, many many games will launch with PS4,
Of Course That's Just My Opinion, I Could Be Wrong
