I saw this the other day and just was a bit lax in getting a news article posted....credit should go to trueachievements.com as that is where I found this information first. I did also note that the Ultimate Warriors pack 4 and Revived Warriors Pack do look pretty similar, but checking other sources (including Kotaku) this is the same list I find. Have fun downloading!
