Now, I'm not saying it can't come out early, in fact, I'm hoping it will. But it seems that the stars are aligning late for the soundtrack to be released the weekend of RTX. Why? Because they know that the soundtrack generates a large revenue, so what's the best way to get con-goers excited for the event? The release of the soundtrack. It just seems highly likely that the 5th of July will be the release date.
(I had a message that was worded a lot better than this one but the reCAPTCHA screwed me over and I had to retype what I could from memory.)
