I think only two more games will reach the million mark which are Little big planet and minecraft.

Not many.

LBP Vita is so close, hope that it reach it before 2015...
And Need for Speed is still selling lol? A few weeks ago it was free in the store. xD
Killzone and Tearaway are doing ok and have some kinds of legs. Someday they both will be million sellers!
Final Fantasy X / X2 isn't doing very well, hope for a good boost with China.
Persona 4 Golden is pretty good.

LBP is now the 4th million seller

Yep, congratulation LittleBigPlanet.

Well like some others in here I'm going to guess no more than 10 LT

It's a shame really, great piece of hardware.

It looks like God Eater 2 could also be a million seller, if VGChartz lists both versions (God Eater 2 and God Eater 2: Rage Burst) as one game. Currently God Eater 2 Vita is listed for 2015 http://www.vgchartz.com/gamedb/?name=God+Eater+2. Could this be a sign that they will list both games as one game?

new saga by square, minecraft, terraway, little big planet vita ,and persona 4 golden imo will be the last million sellers

If God Eater 2 and Rage Burst are combined then chartz might as well combine MH4 and 4 Ultimate.

OT: I don't expect it to get any more million sellers.

Really, not even Minecraft or Persona 4: Golden? I can see Minecraft doing 2M lifetime.
