But, as Canon has shown us with the Powershot S100, they don't have a problem reusing model numbers.
And the S110 aswell.
At some point, old technology is forgotten, what with the playstation and i-phone generation. Remember when music was on big black vinyl discs, and nobody bothered calling it 'analog'??
You really don't have to specify a technology when another technology did not exist. Cameras used to use film, and one did not need that a camera was a 'film' camera, and music came on records, 4 tracks, 8 tracks, reel-to-reel, cassette tapes, all these are analog, but one does not have to state it when it preceeds the invention of digital means.
Now that we've all had a little fun with 'D', how about 'L'? I'll go first:
Ludicrous (as in prices, for 24-70 II, supertelephoto IS II versions, 24 IS, 28 IS)
Languish (as in interest, in lenses that take years to go from announcement to shipping)
