Well we will find out within a couple of weeks if this is real, as they say they plan to release it by then.
A video is suposed to be released before hand aswell...
If the Epsilon is shown to be real, then that basically answers if the modchip is real.
Theres no real reason to believe that the modchip isn't real anyway...
Other people have already managed to get two flash modules working on one psp with different firmwares on each.
It was only a matter of time before someone got round to putting it together on a modchip and making money. :p
Besides, there are now a few website planning on selling UP now, and saying they are expecting stock soon. :)
