Sony Doesn't Deny PSN Schedule List
"Internal working documents naturally have proposed dates against titles, but these change frequently and dates are not confirmed until issued as part of a press release or formal announcement," the statement reads. "The same applies to titles of games, which may be working titles or placeholders subject to later confirmation. As a result, no weight should be given to titles or dates that appear in this document, other than to those which have already been formally confirmed."
In plain English, as you can see. Interestingly, though, the list wasn't denied to be official, which may mean it was indeed, real. So if all goes according to plan over at Sony, we may very well see a lot of that content find its way to our PS3s as specified in the list. Lastly, when asked about the new Ratchet title, Sony declined to comment...which means the probability of it being real is quite high.
