I see they have released the Cascades Roadmap and the Webworks Roadmap ...by the looks of these the OS is really near completion and should be a getting better demo come BBJAM Americas. I also hope we see these beta phones they were talking about, maybe those were the one N4bb sources were talking about when they said we could see a sept. release before hearing about the delay...
I certainly am encouraged by what I saw too. Indeed test devices could help by breaking cover. Something tells me RIM still fears the Osborne effect even this late.
