Kingdom Hearts Entry Coming to Mobile?

In a interview with Famitsu weekly magazine, Kingdom Hearts director Tetsuya Nomura stated:

There are interesting things being planned. Their will be various things, I think, like information on KH3. KH3 development is coming along well, but I also have other new announcements connected to that. I think I'll be able to announce one of them before long: an expansion of the series onto smartphones.

What do people think? Could this have potential, or is this a waiting nightmare for micro-transactions?

Whether you love the mobile industry or hate it, one things for sure: Kingdom Hearts isn't ending anytime soon.
