so if i buy now will i get a code for steam when it comes out over there?
no code for steam on purchase. Steam and Itch are two different stores, if you want to own it on steam I would suggest waiting for the release there.
Will there be a difference betwean steam version and itch io version in terms of future content?
Nope, both are going to be updated at the same time. Same with any other future stores the game will feature on.
I guess one difference will be the steamworks api integration for sharing content and whatnot. But other versions will have something similar as well.
