That doesn't necessarily help. For any technology there will be a price vs. expected sales volume curve and thus a sweet spot that maximizes revenue. It's possible that people have looked at enough numbers and figured out that the interaction between the demand curves for memristors and for flash is such that they can more easily maximize revenue by delaying memristors.

For example, pricing memristor based drives exceedingly high will still likely put them well within the price range of ultra high-end flash based enterprise level drives (such as card based multi-terabyte SLC based drives), and so will still result in a canibalization of flash sales.
