I wonder if the current owners will ever consider open sourcing Supreme Commander, the spiritual successor to Total Annihilation.

I do personally know some of main developers and they know who owns the IP, but to push something like that it will take some resources unfortunately. So might be if some people get together on this it's could be done.
It's wouldn't cost some immense amount of money, but it will certainly cost some. At least I pretty sure that source code for the games is not lost.
They also have patches, but they obviously limited since it's all just patching memory.
Similarly, TA's source code never got released, and while Spring is great and ArmoredFish made good progress with RWE, I wish that code hadn't gotten lost either.
