There won't be a 360deg view, not in the next 3years.
All tilles would need to be remade in 3d, ground textures, rocks, trees, grass, walls, buildings, shelvs, tables, tents...all of it. Then all maps would need to be recreated using the new tilles.
But there's more! There would need to be a engin upgrade to optimize each map (send geoms to the gpu in bigger batches not one by one).
