Came across this on TFW2005:
More Unofficial Fan Produced Transformers Images from Cybertron Con

Contained in this post is also a statement from FansProject about their future releases:
Remember the prototype storyboards shown off at TFCon last year? The Junkion "Collector", the Glacialbots custom combiner group, and the Warbot based on Broadside? These are all confirmed to still be in the pipeline. The Junkion will come in three flavours, male, female and elder. Any one can ride on the back of any other in bike mode. The Glacialbots are still in very early stages but the intention is for them to have a very Generation 1 feel "but more fun". Lastly, the Warbot Broadside is coming along well, and we might be able to look forward to some prototype images of this follow-on to the popular custom piece Warbot Defender soon.

It would seem that the 3rd Party Transforming Robot market is starting to really build and gain momentum.
