I found some info for the new gameboy:
So far, Nintendo has not released much information about its next wave of consoles, and the GameBoy Evolution is no exception.
The next console in the GameBoy series is said to have a flip-top "clam shell" design similar to that of the GameBoy Advance SP. Games for the system will come on mini discs, instead of cartridges, and it is likely to be backwards compatible with the GameBoy Advance (and possibly GameBoy) games, however, probably won't feature a cartridge port for those games. Instead, an external device may be used to download the games off cartridges to a hard drive on the system.
Graphics are said to be of 128-bit standard, and better than those seen on the Sega Dreamcast. Bluetooth wireless networking will be built in and the system will have a lit screen, like the GameBoy Advance SP.
The GameBoy Evolution won't be available til sometime in 2006.
Nintendo GameBoy Evolution Technical Specifications
* CPU: ~128-bit
* Communication: Bluetooth wireless networking
More information and specs for this system will be listed as they become available.
hmmmm. PSP better watch out, cause graphics better than the Dreamcast could kill the (or "my") PSP.
