Roku owners looking to go discless are one step closer, now that Amazon Video On Demand will be available on the box after a free software update in early 2009. Fulfilling the promise of more "big name" providers to come, flicks like The Dark Knight, Pineapple Express or any of Amazon's 40,000 other titles can be purchased and played back to the TV for a 24 hour window. The bad news? Max bitrate is an h.264 compressed 1200Kbps. Not bad if SD only is your bag, but we're even more eagerly awaiting another Amazon VOD HD rumor.
