I have to admit it: I just had to look at the new planets for Dominion myself and they indeed look great!
A friend from corp though got even better pictures made as he went much closer than I. It was nice to see the UI improvements as well. Especially the fleet finder and the mail system look great! As I don’t use the in-game browser anyway, I am not too frilled by it, but it was high-time for an update of both (mail and browser).
The new Asset window is nice as well! Finally we get a bit more help to search through all the stuff strewn all over New Eden (I especially like the tabs that let you e.g. show only modules or ore).
So I am quite looking forward to Dominion. Only sad thing is the Mothership affair which sent those behemoths back onto the drawing board. The affair - in addition to quite an outcry among the players that actually hope to use those ships - probably only got so big because it was a bit badly handled by the responsible developers. Just found an article about it on a German MMO news site called Buffed titled: “EVE Online: Full speed back captain.” (Which sound's a bit too drastic though).
