The Tizen experiment seems to be driven more by a desire to distance themselves from Android. I can't see why they would introduce an Intel based device. They have their own ARM design, good, captive fabs and a product line that is doing very well.
My expectation is that all the Samsung phones willl be ARM.
Problem with ARM is that it is severely limited in performance and power (good for real cheap low end smartphones sold in China). Samsung needs to cover their bases, in case X86 smartphones start winning big.. What better way than to try it with Tizen.
Samsung confirms it will begin selling smartphones based on its Tizen OS this year.
The phones will likely feature Intel processors, given the chip giant's role in co-developing Tizen. Samsung is undoubtedly trying to lower its dependence on Android, but whether it succeeds depends on the willingness of consumers to embrace an OS that will initially have much less developer support.
A Japanese paper previously reported NTT DoCoMo will sell Samsung's Tizen phones.
