Hardly post-Lefevre. The 20.1 is a virtually identical pad, indicating that they at least began the design journey together. Given that CCM is known to work 2-3 years ahead it's really no surprise that they both took the same design and put their own tweak on it.
Personally I think the relationship with the Lefebvres ending works out fairly well for both parties. CCM is no longer stuck fighting with their gear designer when they want to innovate. They've been stuck just putting out warmed over gear year after year, despite having some really good R&D going on. The Lefebvre family gets to cash in on the work they did for CCM and continue to have a big name/money partner as opposed to trying to find the resources to navigate the world of goalie gear as an oddly sized entity (bigger than Passau/Kenesky but not as big as Bauer, CCM, etc...). The real winner is True, who was able to move in and obtain a ready made production line AND client base.
It will be fascinating over the next 3-5 years to watch True and CCM products diverge. One slight difference I've already seen between 20.1 and Axis is that the Lefevre 590 glove I had the chance to try on felt EXACTLY like the CCM 590 I had last year. The Axis 590 is a better feeling glove with a slightly better closure and it feels like CCM has tweaked where it sits on your hand just a bit. To me it's and improvement, but hardcore 590 guys may feel differently (I moved over to 600 for my Axis set). 12.2 and EF5 pads are obviously showing differentiation between the lines and I'm guessing that by the time we get to 12.3/EF6 there will be no more commonality between them than you'd find between those pads and the Vaughn V11 or Brians Genetik VI (or whatever they're called by the time we get 3 years down the road).
