$2499 for 24-70II to well under $2000 in just over a year.
$1699 for 24-70 f/4 to under a $1000 street price (as cheap as $899) in less than a year.
$849 for 35mm f/2 IS to $549 in about a year.

It shows their overpriced policy backfired and supply was over demand making the lens drop in value
Probably not. More like a variation of first degree price discrimination. Canon has a price that it willing to sell at for a profit. Anything they get above that is gravy. Early adopters are willing to pay more, and Canon is turning that willingness into additional profit.
