I don't think the turn based combat is that big of an issue. Both DOS turned out fantastic and there are some features of the tabletop that can be better implemented through TB such as surprise, which was present in the reveal.
The problem is that it looks like a DOS mod, both grafically and gameplay wise.
Also if they are going TB I hope they make a perfect translation from tabletop to PC, which is not viable using RTwP. However there seemed to be a LOT of stuff missing, including race features.
