if this actually does come to market in or around 2015, would it be feasible to replace sql databases with blazing fast redis databases entirely?

Or blazing fast sql databases? Those are two technologies solving rather different problems, I'm not sure how the underlying storage is going to affect things very much.

Redis is so fast because it sits in memory, sql relies heavily on hard disk

Getting good relational DB schemas on REDIS is hard (read: not designed for that). It's mostly for flat data.
