Right now I don't see them up on realtechniques.com, but I suspect they'll be up in the near future. I won't waste your time trying to explain the brushes since 1) I haven't seen them yet except for the videos and 2) Sam does a much better job explaining in the videos. So hear are the Brush Video Tutorials:
Expert Face Brush
Fine Liner Brush
Setting BrushI wish I had pictures for you guys but like I said I didn't see the new brushes on the website yet. I'm most excited for the Expert Face Brush, it looks like it would be awesome for blush and contour applications with cream products. It's not a brush so easily found in drugstores. The Setting Brush reminds me a bit of the Mini-Powder Brush from the Ecotools by Alicia Silvertone Brush Set I reviewed a few weeks ago (review here). And it just so happens I've been in the market for an eyeliner brush like the fine liner brush for a while now so it looks like I'll be picking up all 3 :)
UPDATE 3/30/12: The brushes are now on realtechniques.com. You can find the setting brush here, the expert face brush here, and the fine liner brush here :) You can find them at ulta.com as well!
