I can understand that staying with older versions might be cheaper in the short term, and I can certainly understand that having to work on so many projects is a daunting task.
However, I do not agree with your statement about Moose. We keep the latest Moose version stable since at least one year, and by pushing people to use it we made it work well. Now, of course, if people simply use Moose, they will probably stay with some older "released" version, but at least for development, we always work and push other people to work with the latest Pharo.
Like that we apply the lean philosophy: if something brakes along the line, everyone stops and checks the problem. It can be painful at the beginning, but in the long run you spend less effort and get less problems.
So, all in all, I think it makes a lot of sense to have development always be based on the latest Pharo, especially if the projects are so close to it (like RB or OB).
