Inafune needs money if he's ever going to make Megaman Legends 3. He really likes the Megaman Legends series (more then Megaman 2, which he is a huge fan of), but he's said it multiple times, he needs $15,000,000 for it. It doesn't seem like Capcom is too sure about it, as the first two Legends games didn't do as well as they thought it would, which is probably why they aren't giving Inafune the resources for it. But, $15,000,000 is a lot of money... The only way I can see that money being made is if the three Megaman Legends series games (including Tron's game) are ported as much as possible. They've released the first Megaman Legends game on the PSP in Japan, why not America or Europe?
Sorry if that seemed a little off topic, just thought I'd discussing the threequel here would be better.
