What are the realities of HF RFI with the latest generation of Plasma TV?

Not at my house. I have two plasmas; one a 42 Hitachi, and a new Runco 55, and no RFI.

TVI from a plasma is a definite possibility. I would take an all band portable, an Eton, Grundig, or similar, to the store and take a listen before I whipped out a credit card.

And yes, I would put it on plastic, because the threat of  a chargeback for an unsatisfactory unit will usually make the most reluctant merchant send the truck to pick it up.

For all electronics there is potential for RFI.  But, there are now minimum standards that never existed before, so there is hope!
Yes, I would listen for interference... at least on my favorite bands, before purchasing!  But, you will probably be OK with todays sets.

I have a 4-year-old Pioneer 50" plasma and have no RFI problems with it.

A friend of mine has reduced RFI from flat panel sets by completely wrapping them in several layers of aluminum foil and then grounding the foil to multiple earth spikes. The only downside is that picture quality is affected and the remote control may no longer work*.

The original plasma TV sets were horrible RFI sources and some hams have reported S9 plus noise as soon as their neighbor turned on his plasma set. Things MAY have improved with plasma TVs but the good news is that most flat panel TV screens are now LCD which produces much less RFI.

I have no RFI from my plasma at all.  Hmmm, although I may wrap it in foil for the holidays!!
