Well that would explain why Sega are being so sweet to them now.
*points to Valkyria Chronicles and Shenmue 3 - sorry, I mean Yakuza 3*
I think that the Ps3 is an equivilant of the Dreamcast, but at the same time I think it will not share a similar fate, because of three things - 1. The console that is supposedly going to kill it is dying before it finished the job, 2. Multiplatform games are becoming mandatory on all third party releases, with high profile games being the only real exceptions (for more reference, look at Condemned 2, Saints Row 2, Dead Rising 2 and Mass Effect 2 - first two became multiplat, last two have been stated by their respective publishers will be multiplat), and thus studios will be forced to develop for it - hell, even Valve said they'll have to learn the ways of the cell, and 3. Sony are just a bigger market force than Sega. Sega was one studio, Sony Computer Entertainment is made up of 30, most of whom are the definitive studios in their genre.
