Yes yes I found it. This is looking good and thanks for the information above about release date.
From Gateway web site (looks to me like R4 won't be able to clone this but who am I to know):
"So we left a few things out you say ? Well if it was so easy then others would have it already, or might falsely make videos of such claims .. anyway we digress .. Both nand saving, which will officially make us 100% compatible with all known roms, and FAT32 (drag and drop) based multirom support are now close to completion and entering into our internal beta testing. As you can imagine, both these features required a major revamp of our hardware's internal firmware, something we had known and planned for from day one so rest assured, unlike others, GW3DS is a fully featured and FULLY updatable hardware design. Our policy has and will always be to stick by our customers and ensure they get value for their money. We will be calling on our beta testers shortly to help us stress test our next big step !"
