I love icons (xicons.com

), I would like to know is how vista will represent icons, at the moment they come in fixed sizes e.g. 32x32, 48x48, 96x96 but all this analogue/dynamic resizing leads me to believe that Vista will use actual vectors.
So what icon format will vista use and Is it finalised?
SO is this the new customisation standpoint for Vista. Back when it was known as Longhorn I read that everything was going to be customizable, not so. Hmm well I would like to warn that although MS think their default skin for XP is great I have to use TGT's StyleXP/Toothpaste Theme to make XP look good, and have to use Cursor XP/3D cursor to make the cursor look good and then Microangelo’s ‘On Display’ to make the icons on the desktop behave like .ANI files (i.e. animate)
Can Vista do all of that, because if not its a step back for me.
P.S. I have more than 4 windows open right now
