Don#t be so sure about that. If consumers choose Sony so will the publishers. They have to make meny after all.
sony: you can resell all your games on our console!
customer: what games? where's CoD, where's GTA, where's battlefield?
sony: riiiiiiiiiiiiidge racer!
I hardly think this is within the realm of possibility. You are saying they will pit what they think they lose in used games against what they are actually making on PlayStation platforms in the last few years, and decide to toss the latter in favour of the former?
The platform holders call the shots, not the publishers.
you are talking like these are two established consoles with large bases. with so little else to distinguish them, publisher support will make or break sony; who have so far have been breaking their backs to ensure that they are making a console that third parties want to work with.
the risk of not factoring in some no used games solution is catastrophic, the undesirable no games GAF box which dreamcasts within 6 months. the risk of factoring it in is losing a little good will while achieving parity with your competitor.
