I think this year saw a huge improvement in Rubicon's kits. The initial releases for the year were good - especially the SdKfz 251, which is an excellent kit - but the M5A1/M8 kits really raised the bar, in my view. Sure, there are still a couple of niggly little issues, but they are such a pleasure to build, and look so cool, that I bought several just for the fun of building them.
Less exciting to build, but perhaps more important in the bigger picture, are the Opel Blitz and stowage set. The Blitz signalled Rubicon's willingness to release less glamourous but hugely useful vehicles like softskins. And the stowage set made it possible to customise (German) vehicles and add stuff to dioramas and gaming tables relatively cheaply.
It would have been great if Rubicon could have ended the year with the release of the Hetzer, M8/M20 and M10/M36 (as intended), as these also promise to be great kits, but I'm sure we'll see them soon.
I think we're all eager to see the first of the 'new generation' figures that have been previewed here, and I'm especially looking forward to the SdKfz 250. Roll on 2016!
