DeltaV 12 - 64bit only?

There was question that was asked during the DeltaV Deep Dive session at the last Emerson Exchange, whether or not the next version of DeltaV would be 64bit only or not.  The dialogue veers off topic a bit, but the question doesn't really get answered.

So what options will be available for Version 12?  My assumption is that the user's recent investment in new 32bit machines for DeltaV 11.3 will not be thrown out the door.

Thanks,
