We got word from insiders (was reported on NeoWin as well iirc) when that recycle bin icon was leaked a week or two back that it had already been replaced, but that icon would be in the subsequent build. We'll probably see something close to final icons in another build or two after this.
Then let's hope 'replacing the recycle bin' is code for 'redesigning all icons from scratch'.
Looking at the evolution of Windows 8 and Windows Phone you can't but feel that their designers have no idea where they are going.
