2D/3D : ok let's crack this, it's not so much of a scoop really, the game will be rendered in 3D. The graphical quality will be much improved by this, believe me. There are also quirks that need to be adressed, but we have the time for that, and this is where I will directly ask fans about specific points along the way.
News : hey what are you calling this ! :) I might release some concept art soon to get your opinion.
RPG / strategy balance : I think HoMM is mostly a strategy game.
Engine : as former NWC material, starting anew.
New features : along with our vision of the game, they are basically the reason why we make Heroes 5. However I cant disclose this now.
