What is the DRM on the retail version of Cliffs of Dover?

[Divebomb]

I am looking at all the places you can buy IL-2 CoD online right now and all of them seem to be STEAM keys. Even from places like GamersGate and GamesPlanet, they are all only selling the STEAM version. I can't figure out what the DRM is on the download version from UBI's own online store.

Anyway if the retail version I've got pre-ordered is STEAM only as well I will have to cancel that pre-order as soon as possible (and straight up just not buy this game at all), so please, if anyone got the disc version yet-- is it STEAM only?

Help!
