At the time it seems  the Tisas is the only Hi-Power in current production, but the Hungarian Hi-Powers sell for ridiculously high prices on Gun Broker, and I think it's pretty clear that while the FN original continues to be sought after, people still desire Hi-Powers, not just "BHP" pistols, and anyone could make money and have success with a quality Hi-Power pistol. 

It's not much different from the 1911 twenty years ago.  Today, few people think about Colt when they go out to buy a new 1911, much to Colt's detriment, of course.  But it's the way it is.  Will it go that way for FN/Browning and the Hi-Power?  I'm not predicting it.  The Hi-Power is much loved but it still has something of a cult following versus the massive support for the 1911.  Yes, it's a massively huge cult following compared to those who love some of the also-ran firearms, but companies will have to think long and hard to follow Tisas into the Hi-Power fray.  I'd like to see it happen--I don't have such undying love for FN that I care that they shot themselves in the head.  At least it doesn't fill me with the disappointment that seeing Colt commit corporate suicide repeatedly over the last decades.

Bottom line--"BHP" and "Hi-Power."  Not the same thing.  And a huge chunk of Hi-Power fans agree.  More manufacturers would just help the popularity of the Hi-Power and introduce it to more people.
