How does it mean nothing? Im sure by now Sony knows what it takes to make a console. For them to say that when at least one console is confirmed to be on the way would suggest that they are well underway with their plans.
Sony does know what it takes. Which is 100% why they should never have got into the hyperbole of stating something so out of synch with what actually occurs. Their timeline is a specific timeline they have internally and though shortcuts can be made, and lets be honest that's what they are is shortcuts, they can't magically make things occur that allows them to suddenly release their system spec at an earlier timeframe. Companies can't exist like that. It is the very definition of magic to decide something will exist before it does and thinking it just will pop into existence at your whim.
Now if they were going with a POS that was a cobbled together PC, or tech they have currently. Sure maybe. But even then they magically have ignored the various issues with console tech fabrication such as OS, case, features, heating, power, specific chipsets, budgeting, contracts, specific timelines within other suppliers for parts, fabrication speeds and so many others. And that's if they just wanted something current to today's features which would be a unique proposition coming from Sony.
It would be impossible if they wanted something with parts that were not made yet. They can't just wake up and say AH HA this part is now created and wish it to be and have it on store shelves. Dev kits aren't finalized kits and actual systems require a completely different first run process for fabrication. From then on you can start to create optimizations. Again this is assuming they aren't putting together a current tech item with your local Best Buy's parts. This is assuming its a Sony project.
Its a process. Sony does know how to do many things. Speaking realistically is not always one of them.
FYI this all goes for all the companies. Every step has to be taken to get to the next one.
The only assumption that can be made is that they all have a general target for system technology upon their systems release and will have timelines set up for those particular technologies needed. Sony, any company, should really just shoot for their technology mark and create a holistic system based on their own target. No need for a dreaded Saturn solution.
