We're far from "sensors out-resolving lenses", even at 54MP. Numerous threads on dpreview in which lens and sensor and optical-system designers weighed in, but to cut to the chase we're probably going to see added system-MTF benefit up to around 100MP even with today's lenses.
Canon/Nikon have no 50MP FF sensor yet because:
1) Sony hasn't made one yet
2) No-one else has made one yet
3) Canon can't make one yet, at least not a "good-enough" one using their existing stepping tech
4) In-camera processing needs to step up a bit to maintain acceptable FPS, etc. Fujitsi may not have affordable ASICS ready yet.
5) 24MP and 36MP models are still out there being sold
That said, Canon/Nikon/Pentax etc would be silly to pass up the opportunity to make 'new' lenses to replace old-existing and re-sell them to the faithful
All part of the deal.
