According to Jordan Watters, AirPlay devices could ultimately dwarf "made for iPod" audio docks by 2x to 4x. Part of the reason for Jordan's optimism is the fact that so many iOS devices have already been sold and that many audio devices already on the market using BridgeCo chips can add AirPlay functionality via a software update, including the nine receivers just announced from Denon and Marantz. "The ecosystem is already there," he said smiling. And unlike iPod docks which are usually sold at a rate of one per iOS device, Watters sees consumers purchasing multiple AirPlay devices for every iOS device sold in order to enable whole-home distributed audio. In fact, growth could come as a "step function ramp sucking into the market," Jordan enthused. In other words, he expects AirPlay growth to be explosive. We'd chalk up the hyperbolic talk to Jordan's marketing role if it weren't for the abundance of anecdotal evidence supporting his claims here at CES. To start with, the company's modest meeting room was packed with interested manufacturers poking around BridgeCo's AirPlay offering. Jordan's also booked back-to-back-to-back with meetings until the show ends (and into the coming weeks we suspect). But what really convinced us was an all-in-one speaker prototype from a major consumer electronics company that was quickly whisked away before meeting the sensor beneath our D300's lens. If they're involved, well, we expect the rest will follow.
