It is possible MSI is already preparing their motherboards for AMD 3rd Generation Processors by it latest BETA BIOS updated:
Need to wait until the 3rd Generation CPUs come out and check MSI Support for your Motherboard Processor compatible list and too see if the RAM you have installed is on the QVL List for that processor.
In my opinion, I would believe the 3rd Generation Processors would be better than using a 1st or 2nd generation processor.
Once it come out you can compare all three processors to see which is superior.
