We went through the transition when we started buying 802.11n devices. For the most part, we advertised this change as preparing our network for higher wireless speeds with 802.11n.
When we cut over to WPA2/AES only on our main SSID we additionally dropped 802.11b support. We were finding that most of the devices that were doing TKIP were also the 802.11b only devices. When we finally pulled the trigger we only had less than 15 complaints from our approximate 2500 wireless users. So if you haven't pulled the trigger on dropping 802.11b support yet, it may be a good time to consider doing both.
