...all of it sounds plausible and is likely on the 1-year-out roadmap. full streaming audio/video should be available with OS 4.3.0/4.3.1, likely due out next month (for some devices). expect some changes with the media player functionality (although perhaps not all that much). the blackberry browser will also get a new look/feel but not much different than the current version - and definitely not vector-based HTML browsing. HTML emails will be supported by the end of the year, but that may be limited to newer devices/OS versions. BIS will also be changing before the end of the year (maybe early next year), so the non-BES prosumers/consumers will have more of an appealing draw with full PIM functionality with the likes of GMail and Yahoo.
In the beginning the Universe was created. This has made a lot of people very angry and is widely regarded as a bad move.
