It wouldn't benefit 360s agenda at all but Id say GT.
If it is your best selling IP, then pump up your studio. Double PD's staff. Instead of taking 2+ years to release a demo (prologue) and another 2 years to release the complete version, make a new entire game every 2 years. For a flagship, it should have launched a year after PS3 with GT6 releasing about a year ago.
Because as impressive GT5 sales are, its 7+ million and counting sales isn't impressive given the gen has lasted 6+ years now. People may disagree but I think time/frequency is critical for the success of a IP, not just an individual game sales.
Cause apparently in this industry 1 year dev cycles = milking. 2 years = acceptable. 3+ years = it better be amazing.
