It's more likely to come from Telltale I'd think, but I don't have a preference. Both have done a great job with the Monkey Island series and I'd be happy either way.
As for soundtracks, I agree that the EFMI soundtrack is nice, but note that a lot of it's music is actually originally from COMI. Not all of it of course, but it's pretty noticeable.
I'm not crazy; I'm sanely-challenged.
