I would say a reason this is wrong, partly, is you look to see what software a system plays. You MIGHT be able to make a case for DSi being tracked separately from the regular DS, because it has its own software. However, a simple revamp like going from Phat to Slim with the DS doesn't count.
This being said, I believe the 3DS should be tracked separately. DSi is iffy because the sales of its specific software are downloadable and not over shelves.
