Yes, let's not get carried away. My own post was more in the sense that while it is sad that half of the QT staff is going away, QT should be able to continue improving fine with a 100 people working on it full time. I am actually not aware of any (popular?) open source project with this number of full time contributors, other than the Linux kernel itself.
One of the reasons QT is very important is that GTK cannot be used by closed source apps in embedded or mobile devices (since it is only LGPL licensed).
