Yes, that's what usually happens, and the most likely scenario.

Given that there are 2 components at play, if the controller that
achieves lock-in can't be matched (either via unmatched cleverness or
- more likely - patents) and is expensive there may be a reason for
vendors of good quality NAND to try a different tack. The "commoditize
your complements" tack.

As for the validity of this scenario, it's just me lighting a candle
to a hope. Chances are that there will be a couple of winning
controllers, they will be acceptably priced, and whatever possible
advantage of raw access will be marginal as to be drowned by the cost
and risk.

As Scott hints, it may well be a missed opportunity. We are pros at
collecting those in the attic.
