Persona 4 Dancing all Night on the Vita

So, um, yeah, Atlus announced Persona 5 for the PS3 today, coming out next winter, plus crossovers and spin-offs for other consoles. The Vita appears to be getting a rhythm game, Dancing All Night, which is different, anyway it'll arrive in Autumn 2014.

I guess Persona 5 Portable will arrive in 2015 or 16, but who knows which portable will get it. Trailer to follow... I guess it made sense to add a fighting game to the series, but is a music game jumping the sharktopus?
