Sorry I missed the inquiry comments about the S1 Pro being on sale. I have not been apprised of any forthcoming sale yet. My personal opinion is that the S1 is so new, it will not be included in a sale this soon. However, the Mother Ship has a mind of her own and anything is possible.
Also, Bose does not do "show pricing". Unless it's a unilateral nation-wide promotion, there won't be any special show discounts. That's been the policy for the last 15 years.
