There are several sources that vendors belong to (like NPES), or subscribe to, to get industry reporting. The data shared in the May 2009 press release you pointed to was from a vendor-contributed and subscribed report coming out of the UK, published in March 2009, reflecting 2008 audit returns for participating vendors including the "Big 3". As this was a WW report, results can vary from market to market, and even since the report window."M2" reflects that this report was comparing volume (meters squared, or square meters), not counting installations.
My original point: once again, at Print '09, we are imaging and gumming Azura TS live. Actually, this might not be "once again", since I believe last year we were showing our original (circa 2004) Azura plate at GraphExpo. This would be a first for the US market, and certainly the first since we've had local production of Azura TS on US soil.
