That is so untrue, Sony has huge connections with the Developer's to give out community tools for modding and user generated content. Hell Halo gives you the Forge editor, farcry gives you almost the entire tools set, Sucker punch did it with Infamous 2. Mod nation racer's, little Big planet, you could create an entire level the way you wanted it.
There are mod tools, and it's growing, Sony touched on this during their conference with Media Molecule, who were using the move and a set of tools provided by Sony to create those puppets. Which they said would be available to the public, I mean Call of Duty and BAttlefield they are closed games, no tools as of right now because they like to sell DLC. But to everyone else there are tools to make user generated modes and content. Some of which according to Sony can get published into an actual game through their process.
So on that field he is totally wrong, but he does raise a good point though, no backwards compatibility and all that he's right. But that was all before Microsoft and Sony made the switch from Power PC part's to off the shelf pc part's. Now that their X 86, the next consoles after these will be backwards compatible. It just took them forever to make these consoles using Off shelf part's because of price of manufacturing. Now that these part's are not outrageous in price to manufacture, its all gravy for them, but still shitty now for us.
I see the good and the bad, but from Jim's perspective it's all doom and gloom.
