Well... we cannot expect too much from SQEX. They're slowpoke with VSXIII, releasing another FFXIII, so yeah, we can give up snes or nes cartridge, that's for sure.
As for the PS3's concern, yes, you can play PSX games on it but from the same region. That's why i've kept my PSX & PS2 (modchip). But you have to admit, this kind of package is mostly for collectors, because i don't see anyone spending near 500 euros (shipping included) to play oftenly with their limited edition disks, atleast, i won't.
