DE, I don't recall seeing that recently so it's probably in one of the forums I don't frequent. Do you think you could find and repost it?
While I can not point to a explicit PGM statement I can tell you that from my perspective, PGM has been very clear that 64bit is not in the works and not even on the horizon. Likely it took a bit of "reading between the lines" on my part instead of "read my lips", but that has always been the take-away-message when PGM has weighted in on the subject. Anything else is wishful thinking or just politically correct speak (both of which is generally the case when this subject comes up.)
So hate to burst everyone's bubble but being around here a long long time does lead to things other than just being old.
