we are volunteer hobbyists and do not have deadlines or timelines. these skins get worked on as a hobby for enjoyment during spare time which for most people is minimal before the hollidays. also the more accuracy and detail you build into a skin makes the skin much more time consuming. so if you must know exactly when somthing will be done I have to say...

lots of new skins are being posted for viewing and will likely get added soon though just browse this forum and see the progress for yourself.
most of the skinners here like to have feedback on their work so they can improve it. post some feedback on the skins in progress let the skinners know your looking forward to a particular skin they are working on. it does motivate you to finish quicker if you know players are looking forward to using the work your doing.
