The solution to Sony's issue here seems like a no-brainer to me.

The answer is to rebuild/rebrand the networking for the playstation with a strong partner like Amazon, Google, or Valve/Steam.

A partner like Amazon for example could bring good e-commerce stability to lend confidence to platform.

Google is also an excellent candidate -- they have the experience with scale and could use a strong partner like Sony to help push their home media platforms (GoogleTV, etc.)
