If we were to guess, we'd say that Square Enix's and Eidos' Deus Ex 3 has a name now -- Deus Ex: Human Revolution.
It's a safe bet, considering that Square Enix filed a trademark for that name in Europe. And then in North America. Human Revolution it is, then.
Deus Ex 3 was announced as a PC only title, but rumors and speculation point to the it making its ways to consoles as well.
