Well, if you read just the quote, you will find what was said proven wrong in both the first and last line:

"we can probably bring perspectives to the table that will be new and perhaps helpful to the guys from Mythic "
and
" but there's absolutely opportunities to share and learn things back and forth.""

This is not Mythic coming over to mess with SW:ToR and bioware not help with WAR. What is the absolute key however, is the entire quotes generic phrasing. It is basic practice, when 1 person/company/etc is placed in charge of another, for the new "boss" to say how it will help both sides grow, but not really mention any hard facts. Notice how he never says anything like, soandso will be coming over from Mythic to lead our server deployment team, etc.

No, this is just a generic required statement so that people don't feel like Bioware is coming to take control over Mythic. It is nothing more than that. Don't worry about Bioware.
