As far as I'm concerned the PS2 is still being updated and sold... so I think it falls in the equation. I am almost 99.99% sure the Gamecube was discontinued and the XBox I know for sure was.
It seems the mods need help with this forum. I have zero tolerance for trolling, platform criticism (Rule 4), and poster bad-mouthing (Rule 3.4) and you will be reported.
