[quote name='FlyingAce39']I can see what you're talking about, but you can use the Game Boy Advance as a controller on the GB Player. Besides, a GB player would take up a whole lot less room than a Retron 5.

My setup at the time wasn't wire friendly thanks to the Wavebird. And a GB Player might take up less room, but that's assuming you keep your GC hooked up (which seems pointless if you have a Wii hooked up).
The Retron 5 just seems like a better option if it pans out: better image quality, HDMI, save anywhere, can use SNES or Genesis controllers, and the system can play NES/SNES/Gen/Fami games. But again, that's assuming the Retron 5 delivers.
