HAHAHA. Did you really think Two Worlds would be a game that would make us crap ourselves?
What people forget is that Two Worlds was an incredibly ambitious game which lacked polish, and the sequel will certainly address that, as the company has publicly acknowledged their previous mistakes, unlike Bethesda, who seem to have ignored all the criticism thrown at Oblivion, which by contrast, was a highly polished gamed that lack ambition.
The biggest non-technical problem for Two Worlds is it's restriction of character creation and generic plotline. However, that is exactly the direction Bethesda moved towards with Oblivion, and some would argue even with Morrowind. And let's say Two Worlds 2 still is still not as good as TES V when it comes out, we will probably see Two Worlds 3 and 4 by the time we see TES VI.
Longer development time does not a better game make. There is a bare minimum for creative construction and testing, but after that you are simply working on an engine that becomes more obsolete as every day passes.
