If only. They'll probably make that one of the last announcements.
The TC's question isn't clear - the title asks what you think the info will be, but the OP asks what you want it to be.
I voted region map/art so I can get a good idea of what the region could hold on the 3DS. Revealed new Pokémon are probably going to be early route derps but I think either that or a new mechanic will be revealed next.
