A bit more info
It appears the 70-200 f/2.8L will have a $200 rebate and there will be an $80 rebate on the 24-70. I'm sure other “L” glass will be included as well. I haven't seen the 100-400 or 35L on a rebate program in a while (in Canada), it'll be interesting to see if it shows up now.
I would expect to see a “buy more, save more” type of rebate program in Canada as well. The current rebate scheme is pretty lame.
I have no information about rebate programs in Europe. I rarely hear about those before they happen. Feel free to let me know if you work in retail.
