Dino Crisis, Resident Evil 2, and Resident Evil 3: Nemesis have of course been in the ESRB.org database for a good long time, but they've each sprouted an additional system under their listings. The PlayStation 3 now joins the previously listed platforms, which one would assume indicates a pending release as PSone Classics. Capcom has already mentioned the games as being scheduled for the PSone Classics treatment, so perhaps the updated listing means they'll be hitting soon.
I for one hope they are getting the PSone Classics treatment soon, as I never did finish the original Dino Crisis and would like to give it another go before admitting I am scared of dinosaurs.
Update: Yes, we already mentioned this. Yes, I feel like a tool for forgetting. Yes, I updated the post to reflect the correct info.
