I think some of them do not realize but cutting things like classes, spells and abilities is mostly a programming decision. Every class, spell or skill needs to fit in. D&D has a predetermied ruleset, thats one part.
That is interesting point of view ...
But i dont think they "cut out" anything (except Dinosaurs, acording to Swen) ... they simply didnt implement it yet.
That is why we dont have any Half-Orc in game yet, their models are not done ...
That is why we cant play Bards, Monks, Barbarians ... they are not done, yet ...
So until Larian say "well, now we are finaly done", we can assume that everything that is missing has simply not been completed yet.
