Which chip architecture will be the dominant in the market for media players?

Here is a short list of the 3 most common used at the moment.

x86
Connected TV using  Intel CE4100 platform.
Limited experience in embedded.
Will try to control and extract money out of value chain and ecosystem.

MIPS
lowest watt requirements on the the 3 platforms but limited support for Rich User interfaces, only support Android and Linux so far

ARM
ARM good in mobile devices, but no experience in embedded on TV, HAs become much better in software and OS support.
