Update: It seems like this is not a new release but rather RIM mentioned support for PowerFlasher FDT.
RIM is really following through with their promises at least on the developer angle. They said that the BlackBerry 10 Adobe AIR SDK beta was coming shortly when they launched the other SDKs and here it is. James let us know that the BlackBerry Adobe AIR website now lists the new BlackBerry 10 SDK. There is no official word on the BlackBerry Developer Blog yet but I am assuming something is coming soon.
