Yamaha will introduce the new surround sound projectors YSP-1100 and YSP-900 at the IFA 2006 next month.

The Yamaha YSP-1100 replaces the currently available YSP-1000. The YSP-900 is the follow-up model to the YSP-800.
I own a YSP-1000 and published a review of it a while back. The Yamaha Sound projector technology is great and saves a lot of hassle with placing and cabling individual surround boxes.

Not much is known yet about the new Yamaha Sound projectors. In an overview report on TWICE about upcoming Yamaha products the new YSP-1100 and YSP-900 are mentioned.
The Yamaha YSP-1100 is supposed to sell for $1,699 featuring a larger sweet spot, RS-232 port, and IR in/out. The smaller YSP-900 is supposed to have an MSRP of $899. See also this Yamaha statement (German) on what they show at the IFA in Berlin.

Online retailer Technik Direkt offers the YSP-1100 already for 1099 Euros in Germany (Available also in black).
