Each year the New Media Consortium and EDUCAUSE jointly publish a look a the technologies on the horizon - both near and far. These have a focus on enagement and collaboration.
A new report linked to the header has just been released.
Also, I recommend you keep up with the technologies, techniques and related research via my blogs (the most recent postings are in the right column above). Each blog is published nightly - 365 days a year. They are available via RSS feeds and via a single daily email from each blog with a summary of three relevant items.
