Sorry to interrupt, but I noticed something interesting that I thought I'd bring attention to. The 2007 fun guides have a layout on the front cover showing different destinations that HiT was planning to release in the Trackmaster range (This guide is a different to the one that contained the Ice Cream Factory; the layout is on that guide as well, but the interesting part is covered up by a red border):
Now if we zoom in to the left, right above Knapford Station, lo and behold, we find our Ice Cream Factory:
However, there's something peculiar about this pic; take a look at the stop/go switch and the (assumedly) dumping platform (the thing the car is supposed to dump into). Notice how they're both orange? If we look at the image from the other guide, we can see that the switch is clearly yellow, and the dumping platform is grey:
Of course, this doesn't really prove anything. However, I was thinking, why would HiT change these two pieces and only these two for a single promotional pic. The track and ramps are the same colors in both pics. I don't see why they'd change those two pieces... unless:
Now, this is purely speculation, and I have nothing backing this up, but you know how the Brendam Docks set had different "versions", which changed the colors of the cargo, cargo car, and crates on the dock piece? I wonder if they planned to do the same for this set too. Might the pink cargo from the Gordon & Toby pic be related to this as well?
