You realize that the DSi has an online store for really crappy games, and the 3DS has an online store for a virtual console for old GB games, and while I haven't heard of anything, I'm sure they'll make 3DSware as well, and I'm sure with the 3DS' capabilities, these games won't be crap.
I would be really stoked about the GameBoy Virtual Console, if not for having watched how the the Virtual Console on the Wii has played out. Sounded awesome at first, but it's slowly died out to the point where there are rarely any new releases, and some much hoped for classics have yet to be seen. I'm wishing for the best, but skeptical.
