Watch: Disney is working on their own digital distribution service for all of their IPs, hence the reason why we won't see Lucasarts titles on GOG/Steam/etc.

But any smart company knows that you can get the most amount of customers by having your titles spread out amongst many services. The only way it would be smart for them to keep it exclusive is if they have proprietary stuff going on, which is what I believe they intend on doing. That sucks for us.

Do you have a source on this or are you joking cynically?

Joking cynically, but with the way things are going (Walmart's VUDU service getting The Lego Movie exclusively a few weeks before the physical releases), I wouldn't doubt it if that ends up being the case.
