I did say "almost certainly never". There's an "almost" there that covers the minuscule chance that it might actually happen.
His (their?) appearances in Headmasters is by far the best (and in fact the only real) argument as to why there might ultimately be a Hasbro version in the future. If TakaraTomy chose to retool the mould for a Henkei version, that's the only real shot a Hasbro Classics Punch/Counterpunch would have. But my point was that if anyone actually wants to have the toy in their collection, there's no point waiting around for something that probably won't happen. A bird in the hand is worth an infinite number of birds that don't actually exist.
