The best thing you can do is wait for whist to answer.
But as I remember he said that there is going to be one resolution only since having more resolutions means more "code GUI editing" that does take some time, but not 100% sure, maybe I'm wrong. :-)
And Marco also said sth on how monsters detect your character, and having resolution above 1024x768, would be like cheating since you can see monsters but they can't detect you, and I agree with that, maybe I am again wrong, lol.
I only wonder is there going to be resolution like 1200X768 (1280x768), sth like that, like in Le Royaume des Ombres since that resolution at least on my display, GUI looks a lot sharper, that NPC talk box too etc......
But should check it out.
