One of the things that CCP keeps talking about are a 64 bit client and the ability to scale for bigger better battles that support better game play.
My suggestion is to use Lumberyard and AWS to port the data over. Lumberyard should give them the ability to port in all the current models they have to the updated graphics engine and 64 bit support. The AWS aspect of it would give them virtually unlimited scalability. Have a big battle come up screw TIDI just spin up more clients. as soon as it drops below the threshold shut them back down.
Just a thought.
