I think someone has become too accustom to knowing a games existence 5 years in advance. If you owned a Wii, I would think you would have serious concerns about game releases considering Nintendo is the only company to keep quite about almost every game release.
If you just wait, I'm sure Sony will release a fair share of games next year. In fact, why would you even care what Sony is going to release next year, there are potentially 40-50 worthwhile games releasing between now and then that should legitimately consume your gaming time.
