I believe that I have read discussions (though not a rumor) that the 45 and 90 TS would be replaced. Or is this wishful thinking on my part?
I read on a website that the TS-E 90mm would be replaced by a TS-E 135mm but at the time it seemed like they were just pulling that FL out of their 4$$. Still no update announcement. A TS-E 90mm replacement (L-series) is the lens I most desire. The current 90mm loses IQ when shifting wide open. Unfortunately TS-E seems to be low on Canon's priorities.
