Which controllers are used most in display clusters application??

Hi,
We want to decide about a development board for building Automotive Display
Clusters(Dash Board) application. Few choices we have are: 

Freescales' Total5200 (PowerPc),
Freescales' iMx35 series (Arm core),
STMicroelectronics SPC560S60 (Arm Core). 

We have a prior experience working with PowerPcs.
We would want to go for one which has the highest market usage in
automotive industry for display clusters (Dash Board) applications. 

I know refrence to a proper market reserach study would help which i do not
have access to. Therefore your guesses and experience will sure help me in
going forward and choosing one.

Also if you have any prior experience with any of the board mentioned above
please share with me.

Thanks,
Jalon.

This is a business decision. If you develop the OEM module, you don't 
have much choice. The rules of the game are set by the car maker. You 
are supposed to do certain things in the certain ways. The car 
manufacturer will only allow the parts that they trust, and the software 
modules that they proved. If you insist on doing the things in your way, 
that means that you take all the risks.

The most popular automotive controllers for *everything* are HC12 
derivatives.

Cost is the other major factor. So chose the least expensive part.
