The thing is we won't know if any of this is real before european PS3s are shipped so they can't be modified.
But remember how ppl thought the PSP UP modchip was a fake and everything. It's not great stuff anyway, but it exists and does its job!
So why not a PS3 Iso Loader?
Something to take into consideration : iso loaders boost console sells. However today Sony loses money on PS3s and lives w/ the money coming from the games. That's why I think it's even more important not to take the loader out before the end of may since if you take a simple way of thinking, Sony will only lose money on a lot of PS3s until they can lower costs if ppl don't buy any game (buying no game is stupid anyway, but hey, some ppl do it...)
