The TRO3145 NTNU section said that the Cougar had been restored to production.
The biggest perk of the Thor II over its predecessor is the podded jump jets. This allows it a bit more flexibility to either go for no-jet configs or IJJ ones. It's a lot more flexibility then the original offered, especially in this age of expanded options.
Interestingly enough, the original Thor may still be in production. It was built by Olivetti on Sudeten, while the Thor II is built by Eagle Craft Grup on Erewhon. True, the Thor may have been discontinued and its lines repurposed for other designs, but the two are not exclusive
