PS3 Walking Dead EP 2 Collection List

Is there a reason Walking Dead Episode 2 for PS3 is not listed as a game for me to add to my collection list? Been coming to the site for a few years now, just recently made an account and am making my Collection list. I see the Xbox 360 version, but no PS3. Can users add info, or do I just need to wait awhile?
