I'll champion any APS-C primes, it's one thing we need more of after all this FF-disappointment lately.
I would have pre-ordered the EFs 11mm f/2.0 if it weren't just a patent. I've got the Sigma 8-16mm, but given how slow that is, this Samyang could be a welcome addition, not a replacement.
(I swear, next time I buy a house, i'm NOT doing it a month before photokina. So many good things flying around and i've got a mortgage to pay. But i can still drool and dream...)
