As Crazyflak said, this is a new mod that will require the new 2048x2048, 24 bit colour high resolution skins to get the full effect.
At the moment there only a few suitable skins that have been created for testing and demonstration purposes. That said I fully expect the "serious"
skinning community to dig out and rework their existing 1024x1024 templates to take full advantage of these great mods. In fact I would be surprised if they are not already on the case as this has been discussed for some while.
For me it has always been about the visual impact - and the increase in both "eye candy" and immersion is tremendous (and I really mean that). As a 3d guy I realize that there will also be some collateral damage - necessitating us guys to improve some models to keep up with the "look", but it will be well worth it.
Realistically we all know that this will not be achieved overnight and there is still some discussion/debate regarding the new optimum "standard" but, as I have said before, the genie is out of the bottle now and IMHO it will not be long before all new skins are produced in this new format.
