Umm, am I missing something? I was under the impression that the SCDS2 was not just a game cart but had that super sweet video processor in it for watching movies on it. In my opinion the DS game capabilities combined with the video playing capabilities MORE than makes this a must buy at launch. The GBA and snes emulation are just super delicious icing on the cake.
I'm REALLY looking forward to this cart, if it is what it's been hyped to be I'll be buying many, many, many of these for friends and to sell on CL to locals.
