Looks like Dave Bautista's invite to SmackDown 1000 came later than he was expecting, as WWE just announced Evolution will be reuniting at the upcoming event.

Mike Rome made the announcement via video on Friday ... stating Triple H, Randy Orton, Dave Bautista and Ric Flair will be in attendance on October 16 in Washington, D.C.

As you may recall, the Guardians of the Galaxy star tweeted his disappointment over the lack of an invite earlier this month -- so either WWE execs got the message or this was a SWERVE. 

Guess it will always be a mystery.
