No fixed f/1.8 zoom exists till date. There is no reason why this lens will be built.
While nothing is impossible, it is highly unlikely because the cost of a f/1.8 fixed zoom will be extremely high. The cost will be such that one would be able to buy a complete Nikon D800, the Nikon 14-24 and a couple of other lenses in its stead.
No business will manufacture something which has no buyers!
IMHO, even if Canon does release the 14-24, it will be a f/4 lens.
Will an F/4 lens be a bulb shaped lens? What would the price tag be?
Almost all ultra-ultra wide lenses are bulbous so it is my guess that the bulbous shape is necessary for the extreme FOV that such lenses offer.
Guessing Canon's pricing is about as difficult as shooting a crisp sharp shot of a chickadee in flight with a 5d2
Jokes apart, I'd guess it will be quite high, right up there in the range of 2000-2500 for starters before it settles lower.
BTW, while I feel that it should be f/4, I'm not too sure whether any such patent exists ... maybe someone can shed some light on this.
