The S.T.A.L.K.E.R. 2 rumor of the day is that Bethesda is taking over development of the game. The source of the info is anonymous but, as always, it's always fun to speculate. Here's a translated quote:
To begin with: what is written below is derived from a very reliable source whom I trust, but it is not official information. Keep this in mind, please.Sergei Grigorovich does not sell brand STALKER. STALKER game by Bethesda and published all the rights to play it. The game makes a number of platforms (console, plus a PC) on the technology of Bethesda, the studio most familiar with this technology. Perhaps Obsidian Fallout 3, or a team in Bethesda, but not the fact. It is important that the studio is not in Ukraine, it is almost 100%.
