Samsung has released 3 new 3D glasses today. All of them are battery operated (active-shutter) and require a Samsung 3D-ready TV with an emitter (such as the LED-LCD C7000 or PNC8000 plasma) and a 3D Blu-ray player (such as Samsung's BD-C6900 that's shipping for $399.).
All of those glasses are now available for pre-order over at Amazon.com, we do not know when they'll ship yet. Interestingly, Samsung's 3D-starter-kit includes 2 pairs of the basic model 2100AB, and costs $350 - so it's cheaper to just buy two pairs at $299 (although the starter-kit includes a 3D Blu-ray movie - monsters vs aliens).
