They spend $400 on an iPad, and $30 on games and apps over 2 years because most of them are free, for a grand total of $430 over two years (made up figures).
Your proposing someone buys a $400 console, then $600 of games, at $1000 every two years, and then buys a new $400 console and repeats.
Most of the content of the newer console will still works on the old one, just with cut-down graphical features.
I'm sure that there quite few users that would upgrade after 2 years to a new console for higher-fidelty graphics.
Maybe an every year update is too much, but a 2 year update model on a 4 years generation cycle could work.
Launch at $400 in 2013, with 5x times the current technology
Launch at $400 in 2015 with 2x the 2013 console.
2017, new cycle.
In this model, which in the end is similar to mine, hardware doesn't generate neither a loss or profit. It's just a way to convey the content..
Taking the model a step further would be to launch Xbox and Playstation no more as consoles, but as content-delivery platform, which could run on multiple enviroments.
The biggest content platform out there are:
- Itunes, music and movies
- Steam, gamingv
- Netflix, movies
Xbox and Playstation could become a 360° content-delivery platform, integrated in dish network setbox, televisions, computer, smartphone, tablet and so on.
The platform holder may decides some specification to avoid an excessive fragmentation of the market.
Apple seems that's going to launch an iOs tv this year, there were rumors of Kinect being integrated in some television... Playstation Suites runs on phones, and so does Xbox Live.
Three main platform:
Apple: iOS+iTunes
Microsoft / Nokia: Windows Phone+Xbox Live
Google/ Sony: Android + Playstation Suite
