I don't see any difference in payout the amount still the same, unlike last year that you can get more rewards compared today. I believe there are many FPGA and ASIC mining RVN with new Algo. Since it is just a program anything from a program can make a new way to mine those coins.
The price of crypto rarely has anything at all to do with things like hashrate etc.
It's clear though that you need to go educate yourself on what an ASIC is. It's already known that ASICs "could" still mine a very limited number of blocks if they wanted to. I think the percentage was something like 3.5%. The only way they could still be mining all of them, is if when designing the chip(s), they made some educated guesses as to what the devs might change in the algorithm and they built configurable options into them. I know I certainly would have. However, Tiger is a much more difficult and expensive algorithm to implement and so it's more likely they wouldn't have added that one in. On top of that, having it in front of three existing ones is also not something someone would easily come up with as a potential option. So the likelihood there are ASICs out there that can still mine all block is pretty damn low.
FPGAs are a different story as they can be reprogrammed. But, depending on how they designed the hardware and what the overall tech specs are of it, they may actually need to redesign them to be able to handle Tiger. Regardless, they'll be back sooner rather than later.
