Not only Citect but the Schneider HMI as well. I do not think Wonderware will be well accepted by Citect customers - The Citect name as is will vanish anyway and it will all be Vijeo Citect shortly.
There was also a rumour some time ago that Omron and Allan Bradley were going to join forces a bit harder than at the moment - they were both doing products for each other - one brand is not compatible with the other brand of course!
The Jolly Green Giant is becoming so large that they are becoming inefficient - added to that all the paper warfare and trying to find someone on the help desk that has a clue! The ones that do are well protected by the not have a clues! You need a good rep to find the right people in Schneider these days.
