Then show it already :celebration:
I wish they could too, but, if you look closely, they're being extremely methodical when it comes to releasing more information about Skyrim. They're on a strict marketing schedule now, and that (hopefully) means a slow, steady flow of facts over the next 11 months. One day will be the "let's finally show everyone how good it looks" day, another will be "the first gameplay trailer" day, another will be "let's show amazing, previously unannounced and unexpected feature X in action" day, etc.
The marketing machine, at its most efficient, keeps you rabid, keeps you hungry for more, while still satiating your appetite
just enough that at the end of each new reveal, you're excited and giddy and sharing that new information with everyone instead of blaming the machine for starving you of new info. When done correctly (Bethesda in particular is very good at it), they accomplish two very important things, simultaneously: they keep their fans happy and interested, and they keep Skyrim's name at (or near) the forefront of the gaming discussion (because the fanbase, hardcoe and casual, just can't stop talking about it).
It's all rather interesting, actually. I'm intrigued to see how they roll out more Skyrim information over the next couple of months.
