I enjoy playing coh and want it alive like you do aswell. Another expansion or well supported mod would just do that, but i think relic is not capable of creating what we want.
^ This.
We've all seen in COH2 what the Relic of today can do.
That's why I think they need to keep their current team on their COH2 platform and get a completely different team in to do the HD (if they ever did) - the new teams scope would be cosmetic in nature and the game mechanics left unchanged, with the exception of say a patch that was 99% based of Tommy's.
Its like a Porsche 911 - its a classic design that doesn't need much revision - you don't see wild revisions just for the sake of making them - that's where COH2 failed.
