Pre-orders for the recently announced Diablo III (PS3) have officially opened for $59.99 and Free Shipping. When visiting the link, you will see under "Platform" three options: PS3, PC, PS4. Click the PS3 logo to access the Diablo III PS3 pre-order page.
Something to note is this item was tagged to ship on December 31, 2013. We still have to see if this date is accurate or made up considering not Chris Metzen nor the Blizzard press release provided a release date.
We do know Diablo III PS3 demo will be playable at PAX East 2013 through March 22-24th. Read more about the announcement of the Diablo III on PS3 and PS4. (Video)
Update: For our Facebook/Twitter followers asking about the Diablo III (PS4) pre-orders, my best logical answer is that SONY has not announced yet the PS4 official release date. Not even the PS4 full specs -- other than it has 8GB RAM. None of the PlayStation 4 video games should have a release date until SONY announces the PS4 release date. I think that makes sense.
