What concerns me, is that every icon nowadays seems to be made of plastic (hi-gloss) and glows every now and then. Do not get me wrong, it is a nice look, but after searching for some 'ps tutorial aqua' stuff on Google, one might get the impression that an icon needs to look like it is a 'domed' kinda sticker. If we wait some months, people will be craving non-plasticy looking stuff. For Renderosity I would like to see some stuff that looks hand-crafted. If I could find some time, I would go after that. It is not too hard to make everything round, or rounded, and add a gradient from white (or a opacity percentage from that) to none, to everything. I think a good challenge would be, to really develop a 'next generation'-look, that goes beyond this. What would stick out of everything else. I would be willing to try something. I guess it would be grungy. Just to be different from the mainstream...
