Kind of in the same boat myself on this. I have had people asking for a home screen more in keeping with the latest gen of the AppleTV interface but don't want to step on the xTV3 guys feet. Again may offer it as an option after they release their stuff.
Well, frankly speaking, I would never made it if there wasn't such a delay releasing xTV3. I'm sure guys put big effort in it and have done their best but, at a times, it seamed that project just died. I offered my assistance at the beginning of it (did not know how to code then) and secondly couple of months ago, when I felt utterly lost in XBMC skinning engine. They wanted to pull it of themselves, which is a decision I respect.
However, as my skin was 80% done at that time I decided to finish it and add some things I wanted to have, making it easier to use for the rest of the family. I also wanted to prove it to myself that I can do it.
As it seamed that xTV will eventually be finished I redid all the graphics (again) to make it look different. Luckily it turned out good (at least I hope it did:-). Needless to say, family was very angry because my graphic skills are even worse than skinning :-) and I was way already beyond time limit I gave this project at the beginning :-)
So, if you're considering new home layout, I won't be adding ATV colors to my skin. I like darker look of it and ATV color lovers can go for xTV SAF or xTV3.
Feel free to use my home page code, if you like, although you might need to re-factor it a bit as it relies on Favourites "hack" I did (I hope that JMarshall is not reading this :-) After all, one of the reasons I released this beta is to see if people would be really interested in simple and lightweight skin like this.
EDIT: I see WingmanNZ jumped in while I was writing this post :-)
