hi i was going to get one but had to cancel my order as im getting married, so may get one at the end of the year.
If you on line poker game is flash based it wont play as the vita has no flash player and adobe are not intendinhg on releasing one any time soon. They have already said that are no longer supporting the portable flash player. so it look unlikely that the vita will ever get it.
the sky go app will be up to sky but seeing that it isnt avaliable for the ps3 i dout it will be availible for the vita either
