I can imagine that WotC is having a heck of a time balancing survey feedback and their desire to drive sales. Even with their product diversification efforts, like VTT, generating hype around the need to "upgrade" to the latest "edition" has to be part of their strategy.
In other words, there needs to be enough upgrades to make buying the revised books (for the "same" edition of the game) worthwhile. I suspect they are working hard on the messaging for that campaign, as well as perhaps adding in options for some of the things we've seen in UA to sweeten the offering.
