I don't think it's me not understanding you. It's you not understanding me, I said pre-planned. Not change the release date. Back in 2011 before announcing anything they should have looked at all their game schedules ect. and asked themselves if it would have been realistic to actually release this thing this year and they clearly over estimated themselves. The sales speak for themselves. Would have sold more if it launched with a better 1st party Nintendo title then NSMBU. That is a game that in my opinion, should have come out in 3-4 years time.
Before 2011 they could have. BEFORE. After 2011, delaying the launch would hurt third party developers.
