I was actually implying that their massive billboard conveniently doesn't have the release date on there...
Well, it's not done yet.
If they don't push Skyrim back before the 3month mark, I don't think it will be delayed though, I also don't think it's likely that it'll be delayed anyway. The staggering amount of manpower they have on the game is pretty impressive, they
can do in 5months, what would have taken a little over a year with Oblivion, factoring in familiarity with the generation's hardware as well. While Skyrim may have had a relatively shorter actual developing period (Not counting concepts and pre-development, though I probably should), the amount of time actually poured into it so far is actually greater than any TES game so far.
We are going to get new Info at E3, anyone thinking otherwise is just silly.
We'll probably see all the races by then, as that's not really a big deal to anyone but the TES Devout.
We'll probably see a new Dungeon.
Dragons are almost a definite. They've already showed them privately, leaving what actually happens up to writers interpretation. I think it's time everyone gets to see it.
Low-chance, but maybe see crafting. I anticipate crafting might be one of those "Shelved for the last moment" because of how it can adversely affect game balance. So it will probably undergo the most iterations and minor changes.
