Could the True Blue Megaton be GTA5, PS3 exclusive?

[Killergran]

^ $175 000 000 is (about) what Take2 made on the 360 version of GTA IV (revenue).

If they would forgo a 360 version of GTA V that is how much they'd lose. So any offer to make it exclusive must be up to or exceeding the that value for Take 2.
