Like I have said a billion times, it is all speculation.
MMAweekly gets its "info" from rumors in Sherdog forums. I'll believe it when I see it in UFC.com.
I don't think Zuffa will be able to buy Pride. Even if the name "Pride FC" is bought out, Zuffa still has to deal with all the top fighters' salaries. As cheap as Dana White is, I don't think he has the balls to even do it.
