It looks to be a sale rather than a permanent price adjustment, much like the LFM-1 Compact + SMS-1 sale that's still in progress. As for the issue of prices being reduced and the $200 credit, I have two thoughts...

First, the $200 credit is for any 990 or 970 owner and is available for the first six months that any next-gen processor is shipping. That means that if a 990 replacement appears on July 1, any 990 or 970 owner would have until January 1 to order that replacement and get the $200 discount. That's the deal Outlaw gave us all last year.

Second, history has taught us that Outlaw tries to lower prices on their processors over the course of their life cycles. Keep in mind that a processor from a smaller manufacturer like Outlaw (or Rotel, Adcom, Anthem, Lexicon, etc...) will typically spend three years or more in production before being replaced. They have to be that way because these companies don't have the resources to develop new models every year, so they get something developed and keep it around rather than releasing incremental changes every year. A side-effect of this is that at some point they will sometimes be able to adjust the price down because parts costs may drop (Cirrus may not charge as much now for a 49400 as they did in 2005, for example) and because they will at some point have recouped the initial investment in development and tooling costs. As that happens, they can either leave the price unchanged and make more off each unit or pass a savings along to their customers.
