The PSVita does not use UMDs, your games either come on the new PSVita Game Cards, or are downloaded from the PSN.
As far as i know minecraft isn't legally available on psVita if it was i would have downloaded it.a modded (illegal) psp however has a game called dragoncraft/lamecraft(crappy version of minecraft) it is very limited to just building.I dont recomend wasting time on it.
the announced platforms MW3 is Wii, PC, PS3 and Xbox 360
There will not be a Minecraft two. Minecraft is still in development, and Notch is not planning on making a second. If there were going to be a second Minecraft, it would not be coming out in the near future.
It is not coming out for DS.
No. Neither is it available for PS3, PSVITA or anything by sony because minecraft made a contract to microsoft.
Should be soon.
It is undecided yet, sorry.
no
