Apparently you can't end an IndieGoGo campaign when funds have been pledged, as the Retro VGS guys find out :

All that sweet escrow money 
I don't get the sales pitch for this at all
it isn't meant to play actual retro games, but play 'new-retro' indie games on retro hardware. wut. with cartridges? double wut.
There's no sales pitch beyond the fact it has cartridges... and maybe even that is ancillary to the fact the project lead bought on the cheap the Atari Jaguar molds. It's just a stillborn idea from a guy who is deeply convicted he can make a fortune off the back of "retro" and that he can crowdfund an hefty wage for the next year.
What the machine is even supposed to do has changed every single week... the only really interesting idea IMHO was making a homebrew machine around the FGPA chip. FGPA can be configured to do "perfect emulation" (cycle accurate) for several systems at once (supposedly anything from the 2600 to upper 16 bits) so you could have in theory a console that could serve as an all in one box able to run the native code of games with an HDMI out and all the modern convenience. I think homebrewers would be very interested in that and some of the retro community as well but obviously it's a very niche market, with small runs, somewhat prohibitive prices for the machine (the NES HDMI was over 500$, right ?) and reliant about passionate homebrewers slowly filling the library. You could probably crowdfund the prototype of that.
Will probably never happen with the dead weight carts in the concept and as long as the project will be headed by a guy combining the worst of being a pink glasses nostalgic
and arriviste.
