NEO -- The Upgradable PS 4K!

Sony is going to bring out a new upgradable PlayStation.The Name of this new PlayStation is PS4K with the code name "NEO".
The release window is unclear, but the schedule for hardware roll-out to developers is black and white: development kits prototype are on their way to studios now. A test kit (debug station, if you like) housed within a non-final chassis - which Sony is asking developers not to show - follows shortly. A second-gen test kit, again not based on the actual retail shell, goes out in June. Sony gives more intensive Neo briefings at its DevCon event in in May, while code submission for Neo-compatible titles begins in August.

According to videogame site Giant Bomb, a number of its sources have confirmed the much-rumoured 'PS4.5' is currently operating under the codename 'Neo' and will feature an upgraded CPU, GPU and RAM.
These sources also claim that from October this year all PS4 games will ship in both a 'Base mode' and a 'Neo mode', meaning every game will operate on the older PS4 currently in circulation and the Neo. The difference being an improved overall performance on the 'Neo' version. The new PS4 will also support 4K, but these sources say not every game will operate at 4K as a standard native.

According to the documents Giant Bomb has seen, the two consoles will still be using the same version of PSN. In these documents, Sony has also stated that that there will be no 'Neo exclusive' titles, a fear many have made since the rumours regarding the PS4.5 started circulating. The report also states that Sony is not allowing for any features or content to made exclusive to the new version, so those that stick with the vanilla PS4 won't be penalised.
