The 3DS needs only 50 - 60% of the full processing power and RAM when switching to 2D. So probably the CPU and RAM of the old models would be enough for "new 3DS games", if they only allowed 2D on the old models.
Since many people don't even care about the 3D effect (I personally love it!)... would this be a good compromise to get these games playable on the older models? It's no ideal solution... the battery drain in 2D would probably be as high than normal 3DS games in 3D... but better than nothing.
