Sony needs to build their entire consumer electronics division around the PlayStation-brand and PlayStation-plattform, with PlayStation 4 as their central communications hub. Their entire main businessplattform should be built around that central communications hub. Hardware systems to be supported in a cross plattform user interface should be:
1. PlayStation 4 [Turned into a Game Focused Entertainment System] (businessmodell spanning between 2013-2020, with a possible successor ready for release in 2018)
2. PlayStation Vita [Primarily used for remote play for PlayStation 4, and as a touch screen controller for PlayStation 4) (2011-2016, with a possible successor in 2015)
3. PlayPhone [Sony's true answer to iPhone] (the first such phone should be released in the end of 2015, in four different sizes; S, M, L and XL, and followed by a new modell with four different sizes each year)
Key is connectivity between these three main hardware plattforms, where each plattform enhances the capabilities of the others.
A secondary businessmodel should be Sony Intellectural Property, where all entertainment and software development, as well as trademarks and copyrights, should be gathered. This includes development, production and publishing of games, movies, software tools, music, e-books and live performances.
Anything else should be scrapped as soon as possible.
