It's not going to be that much less than it would cost to buy a Ps4 and Vita separate. So say (In the US) the ps4 cost $400, and the vita cost $200. So $600 separate, it'd be likely Sony makes the bundle like $575 or so.
It would sell more obviously if it were cheaper, but you don't want to make it too cheap without lowing the cost of the vita itself.
