Chances are high ZeniMax will use their usual methods to buy out Obsidian and if that happens, seeing them develop some TES games would not be surprising. Besides, last time I checked it was Bethesda that was removing features, game mechanics and over simplifying the Elder Scrolls franchise, not Obsidian or anyone else. Obsidian as a general rule of thumb would resist such over simplification if they had creative control.
Well seeing as how fallout 3 outsold the original fallouts I would say that the consensus among the original fans isnt worth that much.
