I've been working on this on and off for about 6 months or so now in between other stuff and its finally about 98% finished.

The main body of the unit is even thinner than the Fusion3 (25mm!). It gets almost exactly 3hours playtime from a full charge and has a built in mempak.
For now here's some teaser pics (I'll post a proper video/pics once the analog thing is sorted out):



If anyone is interested, This unit will be up for sale once the analog thing is sorted out. I'm looking for about $700 for this one, I'll even toss in the 64 Drive I have here. I'd prefer to keep shipping to within the states, unless you're prepared to eat some crazy registered/hazmat'd shipping costs for international buyers. If anyone's interested just PM me, first come first served.
