(CW1) Canon having Problems with Glass Supply?

Northlight Images reports a rumor suggesting that Canon’s…
glass supplies (more exotic types) are limiting the introduction of a whole load of new top end lenses. Canon has new manufacturing capacity, but optical glass making still takes a lot of time and is not just something you can just quickly ramp up
Sounds unreliable to me, and never I got any suggestion pointing in this direction. For me it’s CW1.
