Sony is doing as well as they can. They probably realize that with the changing landscape they need to do different things and TCL might be the right partner for that.
For example, they have been working on new RBG LED for 2 years or so, only to be proven it can't compete in real life with the traditional tech that TCL is pushing this year, albeit some notable improvements. The panel was TCL for sure, but the bet was Sony. TCL has multiple bets and than decides which one has a long hand.
We all want Sony processing, but not at the price Sony requests, especially being two steps behind the hardware game, and just trying to hit the reviewing marks to win the game. This will work out well for the consumers in the long run unless TCL gets greedy.
