On their Twitter feed, they have the same picture of Gabriel by the waterfall staircase.
I can only hope that if they are working with Castlevania, they avoid Lords of Shadow 2's pitfalls and bring in things that made the first and Mirror of Fate fun and enjoyable (art direction, visuals, nods to classic games) while bringing in something fresh.
If they aren't, then best of luck to whatever they are working on, and then we'll see what's next for Castlevania, if there is anything.
