Still, E3 is an announcement convention? So, this has all been a rather lame and stupid "carrot dangle"...
Feed the carrot to the donkey, you don't get led to the market, I suppose.
Anyway, looks like my wish list is well and truly out the window (1. Dawnguard refers to the moons, which 'protect the dawn' i.e. Lorkhan keeps the world going, and you get to do moonsugar and travel to them with the space Khajiit and repair the void night forever. 2. 'Dawnguard' is the name of the Maormer flagship. Ah, well, never mind).
Dawn era is still possible though, to the Nords, the Dawn era wasn't the beginning of this world, but the end of the last one, or indeed the end of this one. Aegnir mentioned maybe you should let Alduin destroy the world, and there is always the suggestion that if the Kalpa doesn't turn, much, much worse happens. What could we possibly have to prevent that is actually worse than the whole world being eaten?
