It's not so much about not being in the play-test it's more about there not being ANY news about ANYTHING. WotC dropped a bomb-shell on us all and then... nothing. Well, aside from some very vague comments from Monte.
But that's par for the course with WotC. They announce something and have zero plans in place to make it happen, let alone market it. It's all pie-in-the-sky until a product is delivered. I've learned not to trust ANY claims made by ANY WotC employee about ANY product that is not finished and on the shelf for sale.
What they should've done is set up a specific news feed site and organised with sites like ENW for 'breaking' news and information in order to build hype and get people involved. WotC made a bold claim that they wanted to be informed by their customers and then go silent; do they expect us to seek them out? Should we all go to Seattle and ask for a play-test package or at least news about one?
Until 5e is in my hands, I refuse to believe it exists.
