Bethesda's Next Game to be Revealed Tomorrow

Kotaku is reporting that the pre-E3 show airing on Gametrailers/Spike TV tomorrow evening at 12:30am will feature the very first information and a debut trailer for Bethesda Softworks' next game.
The show will air the first trailer of whatever Bethesda has up its sleeve, giving fans ample reason to tune in. Of course, if you just want to see Spike TV's Geoff Keighley and sundry game industry types wearing the dressed up, dressed down t-shirt and blazer combo on camera, the GameTrailers TV E3 First Look special will oblige. As previously revealed, you'll also get a look at world exclusive premieres, including first footage of Mass Effect 2, DJ Hero and much, much more.
The Elder Scrolls V? The Elder Scrolls Online? Fallout 4? Or a non-RPG? It's anybody's guess at this point.
