March is likely, but I wouldn't be surprised if we see alternate iPads in march for a more consumer-focused line, along with some much coveted new Watch bands. Then Pros next fall, with minor bumps to the MBP.
Also keep in mind that only the MacBook Pro saw updates. That means MacBook, iMac, Mac Mini, and Mac Pro are still on the horizon. We could see them in March with the new 10.1" iPad.
