Pros Yamaha updated firmware for both YSP-4100 and YSP-5100 and both support 3d. Nice thing is you don't have to run wires and its simple to operate.
Cons Only problems is price and its too tall meaning you have to raise your TV so that its not covered up by the huge speaker. When yamaha lowers the price to 1300 dollars which is still more than 2 times most other systems its worth buying.
Summary Good enough for people that don't wish to run tons of speakers and wires, but still would like surround sound
