I saw that too, a price increase occurred last year as well. If I recall around the same time as ICC.
Probably just start to expect it on a yearly basis until proven otherwise. I have to try and bite my tongue because of how good the software is, but it isn't perfect and yearly pricing/structure changes will start to make it difficult for an integrator to maintain accurate quoting to their clients. When I first purchased v7.7 "The Works Limited" in May of last year it was $6750. Today with the new pricing and having to customize the purchase to get the same modules to match what you got with "The Works Limited" package originally, you now pay $10,646, a 57% increase.
Looking at the 'Works Critical' (with redundancy) that came in at $26,950, now it's $33,893 a 26% increase.
The changes with the integrator program compound my feelings even more. I just maintained my 'Core' certification and let my 'Gold' certification lapse. Core was a lot of time and effort, and since I was grandfathered in I didn't pay the $1000 fee. To expect 100% correct answers on IU and on the exam, I probably spent 60+ hours on it.
I understand that there is a reason for the increase, and hope it's to pay their people what they are worth and for the continuous improvement of the product. But I would really like to seem them put some hard numbers to their business and show everyone just how well they are doing in the market rather than bouncing around that question by saying their product is so different that they can't really compare themselves to anyone else in the market.
At the end of the day, New SCADA or not, your competitors are FTView SE, Wonderware InTouch/Sys. Platform, iFix, GE Cimplicity, WinCC. Cut back on the marketing BS and put the cards on the table, you have a great product, lets see the results after 5 years.
