Crystal Dynamics new game to be announced soon. Legacy of Kain reboot?

Looks like Crystal Dynamics is gearing up to announce a new IP that they are working for some time. The CV of Matt McCulloch had the following line at Linkedin:

Creating wildly cool environments for a soon to be announced title for Crystal Dynamics.
Last year Crystal Dynamics confirmed they are working on two new IP beside Tomb Raider. This is probably one of them.

It is heavily rumored as a Legacy of Kain reboot. In last February, Square Enix registered the domain WarForNosgoth.com. War for Nosgoth is a setting for Legacy of Kain series.

Last game in the Legacy of Kain series, Legacy of Kain: Defiance was released in 2003.

Whatever this game is expected to be a next-gen title. There is a good chance of it being announced at Microsoft next XBOX reveal on May 21 or at E3 2013 next month.
