As to how long it's gonna take, Idunno development cycles for complex technology like this can often take a decade, somebody would have to pour enormous resources up front into fast tracking it. You could maybe halve that time then to five years if you started a company devoted exclusively to creating the new engine.
I'm also noticing that a lot of them look a lot like aerospikes due to the nature of the combustion chamber needs. This will make them most ideal for second stages.
