Well, I'm sure that if it is indeed real, once it is released it will be taken apart, and dirt cheap clones will be made. Vaguely interesting IMO (not that I have a PS3...), but if it does indeed use official SDK stuff and is therefore completely illegal, I hope someone reverse engineers it and makes a legal version for loading homebrew or whatever.
EDIT: I wonder how early in the boot sequence the check for the device is made...if its very early (e.g. equivalent of pre-IPL on PSP, as it is with Pandora battery), this CAN'T be patched with updates. Only newer hardware revisions. However, they do mention that they can't guarantee operability over 3.41, so I am guessing it may be later in the boot process, meaning it can be patched...I guess time will tell.
