Weren't people thinking this when there was a switch from the Gameboys to the DS? If you don't buy this system, you can't play, ever again? All systems are put out eventually, I guess it's the DS's time. =/
I remember getting my first DS in 2006, and I was just lucky that Diamond and Pearl came out in 2007. I also still have yet to get a 3DS, and with the slowing of DS game production, I am bound to get either a 3DS or 3DS XL this year.
