Yep, it's mostly likely heading into that direction (iOS, Android, Windows Phone).
Would be great to see a new HD Ecco though. Think about it, they could do something along the lines of a more traditional adventure game, but in an open-world context. You'd have main story quests, gain powers, use those powers to discover hidden secrets, easter eggs, etc.
But... I hope they don't include sharks... It's one of the reasons I never actually finished Defender of the Future on the Dreamcast (btw, check out some the gameplay videos, 'cause for a non-cell shaded DC game, this one doesn't look like it aged at all.)
