A minor but important point is that they aren't advertising anything at the moment. We're looking at text from a survey, and not an announcement from WotC.
Having said that I have little confidence in WotC's abilities to create an online platform that satisfies my needs completely, but if they would create a service with functioning tools for character creation and campaign management, and ad exclusive game expansions to that mix, I would give it a try.
Much as I have tried most other tools. Which haven't worked with how I want to do stuff, so that's a pretty high hurdel for WotC to clear. Not so much the technial stuff, but how the user interface work.
