RPGVault has posted up an article entitled "RPG Developers at E3", which gives a rundown of what to expect from each one at the E3 expo this year. The article talks about developers such as BioWare, Blizzard, Artifact Entertainment, Mythic Entertainment, and Bethesda Softworks, as well as the games they will be featuring, such as Neverwinter Nights, Diablo II, Warcraft III, Dark Age of Camelot, and Morrowind.
Along with what to expect, the article also includes quite a few different interview snippets from the various development teams. Definitely worth a read.
