My favorites are Kingdom Hearts tied with Zelda. It's very difficult to say if the KH series is on a decline, while KH2 sold less than KH1 I think that has more to do with it releasing near the end of the PS2 life and I don't think the handheld games are a good reference since their lower sales could be because people see them as spin-offs (though they really aren't) since they don't have a number in their name like KH1 and KH2.It's also difficult to say if KH3 will sell more or less than KH2 because it's been 10 years since KH2 and the market has changed since then but I can see KH3 being bigger than KH2, especially if it includes big newer Disney properties like Frozen, Tangled (confirmed), Big Hero 6 (this is confirmed too),etc. Regarding Zelda I think the series has more or less remained stable and I think Zelda U will sell more than SS if it's on NX and if the NX is successful.
