Harbinger of the future of 2-channel?

I just looked at the Sunfire website and noticed that Sunfire no longer makes 2-channel amplifiers. The minimum number of channels you can purchase from them is a 5-channel amp.

I remember when Apple came out with the I-Mac. It did not have a floppy drive. Even though I hadn't used a floppy in years, it still made me a little nervous that the machine didn't have one. It turns out that Apple was right on the money by eliminating the floppy. Email had rendered it useless.

Is home theater pushing 2-channel closer to the brink?

Does anyone think that the bulk of amplifier mfgs will follow suit and concentrate on multi-channel amps? I see that Audio Research has a new multi-channel preamp in its lineup.
