If they announce a Skyrim movie I will probably stop watching their conference thingy.
I kinda agree with Pruitigoe, it doesn't have to be a game from Bethesda game studios at all.
DOOM will probably get some mention I'm sure. Dishonored 2? Well I haven't finished the first one yet, so I'm not sure if it builds up to a sequel or not. If it doesn't I'm fine with it not being a franchise, however they might still have other news from Arkane.
New tech? Creation Engine 2? meh...
Skyrim movie? As I said, I personally have zero interest, I know that some other video games are getting movies or there are rumors of them getting movies, but in all honesty, can anyone name 3 good movies based on video games? I can't even think of one.
Fallout 4? Yeah sure, I would probably bet on next year rather than this year though, but whatever. But Bethesda releasing two games back to back like that? Probably not, I don't think they would give us TES the year after because, it would probably ruin sales of TESO in some way, I don't think they will give us TES news so soon after TESO goes free (well, no subscription fee). Another reason, I can see a lot of people skipping fallout 4, I mean, I probably would, if it's just like a year apart. I would probably save my money for TES, maybe get some of the non.beth games coming out and pick up Fallout at some sale later on. Yeah, I'm not made out of money, and so close releases is one of the reasons why I don't buy CoD or AC. Either way, unless they all of a sudden have another team working for them I struggle seeing how they would release two games that close to each other without one of them being a buggy mess.
So I think they will announce maybe one game, probably Fallout, but it could be a new IP or something. And then give us news about DOOM etc. and maybe one or two other games from different studios, like Arkane and maybe another one.
