They are probably getting ready to show the character system (armour, perks, spells, etc...) full blown in game footage (5 mintues of actualy gameplay) will be shown at E3 as people will want to test this game. E3 will launch a new set of articles based on the game testing from the general publec and media with a new trailer to boot
I remember hearing that factions were something they wanted to talk about later a specific time. Could be that as well.
In the mean-time and after, I would like to see some developer blogs on how they've created the new trees, flowing water, fog, this snow that accumulates realistically with no preset textures.(or it changes the textures...I think a lot of people are confused on how it works. It would be nice to get a clearer picture on what the company is talking about.) Any other area of design would be great too.
