Every version of Deus Ex: Human Revolution is going to require Steam to play. DE:HR is in the Steamworks RETAIL SUPPORT list. And there is a offical statement:
LONDON, UK - DEUS EX: HUMAN REVOLUTION™ is making a triumphant return
to its franchise PC roots, with digital availability on Steam®, the
leading online platform for PC games and digital entertainment, as
well as in boxed copy form at retailers worldwide at launch in August
