Apple's plans for new AirPort hardware were cemented Tuesday after an FCC filing showed a new AirPort Extreme station. Known just as the A1408, few details are available beyond that it would have a 3X3 antenna layout, likely to get 450Mbps peak speeds. Although the online Apple Store is still up as of early Tuesday morning, the FCC filings have the details due to go public the same day, suggesting Apple either launches now or in the very near future.
