not even close. it would be very surprising to me if cern is getting rid of their labview dependence, as it will undoubtedly increase their development time and robustness (if they are doing things right).
I'm not even sure where the notion appeared that they have a systemic, large scale labview dependence. I always thought their data acquisition pipeline was a lot of custom electronics, piping data into fibre-channel? Not exactly sure, how labview fits in there?
i know that they use labview and national instruments for some components, but my comment was more along the lines of "if they have some large dependence on labview and ni hardware, then [it would be very surprising...]".
however, it does seem they have used it a lot, at least in the past. they have a site license (which is uncommon except for universities) and what appears to be a large internal component written in labview.
