DQVI, DQMJ2, Nunokuni, and now new Pokemon... DS RPG lineup for 2010 is set... I don't even think DS2 will be announced this year. The momentum from these RPGs would be enough to carry DS into 2011.
MikeB predicts that the PS3 will sell about 140 million units by the end of 2016 and triple the amount of 360s in the long run.
