Sigma already makes a 14mm f/1.8 for EF mount. It got good good reviews, including for astro, and is only 75% the price of Canon's EF 14mm f/2.8I don't know how many of these will come to fruition (or how much they'd cost), but I like the way they're going on the fast ultra-wide.
14/1.8 - Wow!
22/1.2 - Wow!
Edit - just noticed that these are EF mount. Might be more defensive patents than anything - that is, Canon locks up the formula so that nobody else can use it.
If I wanted to buy a 14mm prime, I'd buy either the Samyang SP 14mm f/2.4 or Sigma 14mm f/1.8 Art, the Canon EF 14mm f/2.8L wouldn't even be on the list. Which is why I think Canon might (not will, just might) turn this patent into a fast ultra wide lens.
[I don't shoot astro, so I bought the EF 11-24mm f/4L]
