Does anybody know if kingdom hearts 3, when it does come out what system it's most likely going to be on?

I figure it's going to be one of the main games in the series like the first one and 2, so it's probably not going to be on a handheld but more the PS3 since the first two console based games where on the PS2, I don't know if there's confirmation yet on that just wanted to know if there was or if anybody else agreed with me on that. Thanks.
