I think that the DSi XL was designed for the "expanded" audience, I mean people who plays games like Brain Training, Sudoku and stuff....those poeple won't probably be interested to spend much more money for a 3D console with better graphics (3DS), so till its price goes down they can still choose the DSi XL at a lower price, for some time (I guess about 2 years).
Still even if they are really clearing the DS stock, I don't see how not overselling the ps2 could be a problem, DS its probably already the most succesful console ever it sold nearly as much as the ps2 in much less time, with probably less prodution costs, not to mention all of the multi-million sellers Nintendo has made for it.
