I'm more with John than Wayne on this one. They are completing the morph of Summit from partner-focused show to end user-focused show. Sage has become quite data-driven (LaBahn seems to live-eat-sleep them), and combined with larger market changes, has decided that Summit is justified by beefing up customer $$ spends correlated to Summit.
Sage 100 and 300 are apparently in milk-mode; you don't partners as much compared to when new-customer sales were important. Sage 50 is clearly end-user pull-through, and if they can get a load of accountants to come and then choose Sage 50 over Quickbooks it's gravy. None of that relies on educating and firing up partners.
X3 is a different game for now, but lead gen for it is more tied to Sage branding and market awareness. I wouldn't be surprised to see the more technical issues about x3 than any other product, recognizing the one partner segment that Sage thinks it really does need.
Just more confirmation that the old days are gone, I think forever.
And the cheesy ""sort of commit to go now and we'll sort of commit to provide something worth your time, partner"" approach is probably more because they just haven't had time to lock down some of the details they need in the midst of the very big change to the show's focus.
