It's certainly not in Apple's interest to let this industry consolidate further [2]. Memory prices have already been on the rise and Apple is using more of it (that actually could be the reason why it's rising).

Hopefully, Apple is planning to single source or majority source their memory through Toshiba, and give them funds to develop more advanced memory on newer processes, as that is what this market needs to develop further and faster. Apple may extend their engineering talent into building their own memory controller perhaps, similar to how they have done a ton of in house design for the ARM SoCs used in the iPhone/iPad lineup, instead of using off the shelf ARM designs.
Also they already design memory controllers. They purchased the Israeli company Anobit in 2012 to do just that [1]. That's why Apple's storage benchmarks on recent products are really good.
