Its worth noting too, that the Gamebryo Engine which was used on Oblivion, Fallout 3 and Fallout: New Vegas was also used on Morrowind which was an Xbox/PC game released in 2002. |
The game was also designed to run on PC hardware that was less capable than the 360 and PS3. My brother managed to run Oblivion on a crappy dual core AMD with an NVidia 7600. They (PS3/360) weren't the lowest common denominator so it becomes very relevant. Assuming they're designing these games for PS4/X1/mid-range PC, then it's quite possible that the 1Gb of RAM in the WiiU just isn't enough for what they plan on doing.
Also, the Gamebyro engine has been updated heavily since Morrowind. Engines evolve heavily over time and incorporate new features that become integral to the game(s). Just look at how Valve have updated the Source Engine since Half-Life 2.
