This is far below what they forecasted last month (14 TH/s @ 1300W). I was hoping we might get a little more, not 20+% less. I love Canaan, but this is making me re-think my purchase plan for next year.

other plan is to what...buy S9's at double the price?

Fair. The price increase on the S9 definitely impacts calculations:

S9 14000 GH/s @ 1372 Watts @ $2725 => .098 Watts/GH and $.195 price/GH
821 11000 GH/s @ 1200 Watts @ $2150 => .109 Watts/GH and $.195 price/GH

Basically, at $2150 for the Avalon 821, you're paying approx the same cost per GH, and it's only slightly less energy efficient. Anything less than that would be a win over the latest batch of S9s.
