Indeed, we are pending an update at the moment. It's not due to lack of content, but lack of time to get it formatted, the RAR files updated, and all that great stuff. On average, it's taken about 1-2 hours to do an update, and once we start, we have to finish, so it's finding that 2 hour time to do it.
With that aside, the main issue here is the new staff at http://www.wstaylor.net
The site is under construction, and is actually in a concept stage, where we aren't sure how exactly to lay it out just yet, so any content may and likely will change in it's appearance. This site likely become the home of the gallery we keep maintained for these wallpapers, thus it's relevance here. I would like to restate the fact that we have obtained the licensing terms for this collection of wallpapers, so as to make sure people are aware that this is in no way illegal content (for further information, you may PM me, and I'll get back with you, or forward you the email conversation with Microsoft, at your preference).
For any further questions or concerns, you may contact myself or wstaylor and we will try to reply as soon as we can. Thanks for your understanding, and God bless.
