The thing is that the successor to the DS is likely being planned (just as most game companies admit they start research on the next system as soon as the current one launches), but since it's now the bestselling system ever in a major region, I think Nintendo will wait until sales slow down, either by time or competition (the PSP's successor).
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
