nine_rpg_sequels_wed_like_to_see_now_that_diablo_iii_has_released.html

Among them are KOTOR 3, Icewind Dale 3, and Alpha Protocol 2.
A quote on AP2:

I couldn’t have been more surprised if I tried, when I put out a call to see what RPG sequels people most wanted and Alpha Protocol 2 came back as one of the top answers. However there is merit to the idea. Alpha Protocol had a ton of great ideas that ultimately fell flat; if polished to a shiny veneer, a sequel could deliver the goods as the game Obsidian originally intended to make.
