V for Vengeance or Vita? New God of War coming

Sony's PlayStation page on Facebook has a little teaser about a new announcement to be made next week. Consensus is that its for the next God of War title, which would be a great thing to have on the PS Vita, either on its own as a PS3/Vita dual release.

The game is one of Sony's more demanded series and did very well on the PSP thanks to Ready at Dawn's amazing effects at cramming the game's scale onto the small screen. Both the original developer David Jaffe and Ready at Dawn claim to have moved on from the series, so who's in charge if it is a new edition?
