with the recent updates of the 24mm and 28mm with no word on the 20mm i bet it's either not going to happen anytime soon, or never. i'd be interested in a wider than 24mm 1.4, but i don't see how they "need it". nobody else has it, and people seem to be doing just fine. it'd be cool just to throw one out there, maybe an 18mm 1.4. sure it'll cost $3,000, but it'll be a cool watermark. i just doubt it, esp with the economy in the crapper. besides, from what i've seen the 16-35mm has that 20mm spot at f2.8 covered and does it better, and if you can live with f4 you'd have to say the 17-40mm has it covered as well. but, what about the existence of the new 24 and 28? they have IS, and i bet that signals no IS wide on the horizon. otherwise at some $800 each what's the point?
