It's not looking good for another TES or FO game unless they're already very well under development.
EA has taught the industry that mega corps are where IP goes to die a long, slow, cash-cow squeezing death. I'm actually more disappointed in ZeniMax/Bethesda. In my mind, there is absolutely no possibility that Bethesda will ever produce another game on the level of FO3/NV now because corps do what corps do which is A/B test and second guess every decision until the product is a flavorless lump.
