They where going up before C19, lead (in part) by the announced price of the Delta and leshly2, RTI and Zbroia put 25% on their new top models over their old top model, other would/will follow, question is will we buy it.
Probably.
Not I...having air guns that are less complex than their counterparts (firearms) yet more expensive makes absolutely zero sense, its a cash grab for people who want the latest and greatest..higher end pcp's is truly a small club and if you don't have deep pockets, you ain't in it. So there is little to no incentive for a 'high end pcp maker' to make reasonably priced or 'budget' pcp's when this club is so small, even though all the parts in a pcp rifle are quite basic and inexpensive...I'll give Edgun the least poop out of the few you listed as I feel he goes a bit above and beyond with his guns from machine work, to stock work, to customer service, he's a stand up producer of high end pcp's that aren't over-reaching being that his models are similarly priced yet offer so much more then most competition. Just my 2c!
