Scam for sure , no one will try to make an asic for equihash because if known the algorithm will be changed and this machine will not worth a penny , and thats a huge risk for developers and users.
But if that were true, wouldn't they have stayed away from any of the 'X' series algo's? Especially considering its 11-15 rounds of hashing? Following your theory all that would be needed to make the bakail X series miners 'worthless' would be to change 1 round of the hashing?
I'm not saying these are real by any means, its pretty well established now that its a scam, but based on your reasoning most ASIC's would never have been made....
Also as stated above
~snip~ but equihash is more prone to fpga than etheruem for exmaple, so in the future it's possible to have the hash rate much higher ~snip~
