ProjectOffset.com has also gone down. Given that Intel acquired them at the same time as Havok and given the rumour and speculation is that Intel will be releasing a version of the engine for development as well.
Game Engine + Havok + Intels existing toolchain = easier PC development.
I must say I was getting concerned that Havok would not release ontime when it was getting so close to the end of May. Certainly good to have more accesible contenders out there other than Physx & Bullet. Should make for some very stiff competition.
