A company is aware well ahead of time of a product's release date. Therefore, they can adjust production and inventory of current models accordingly.
No one is asking for specific dates. Rather, many of us simply want to know whether a product will be released, at all, in our market. Secondly, it would be nice to have an approximate release date according to their best assessment. It's ok to say a product won't be released for 18 months. We can't speed up development, production, etc. But at least say something. It is also ok to say a product won't be released at all in a certain market for whatever reason or no reason at all.
I don't think that knowing a product is going to be released in 9 months, for example, would cause sales of the current generation tool to go to zero. I have two very good examples of that. I have known about the new Cleantex vacuums since their release in Europe. That did not stop me from buying a CT 33, why, because I didn't want to wait ad infinitum for their North American release. I have since bought a second CT 33. Similarly, I have purchased two C 12's despite knowing about the new C 15. I will enjoy using these tools and if I want to upgrade to the latest and greatest when they are available, I can sell my current tools for a very good price and do this.
One of the nice things about owning Festool's is their very good resale value. It amazes me when I see beat-up Festool tools selling for as much as they do. Think about that, if they were owned by a professional, he made money with the tools and is still able to get a large percentage of money back when selling them.
Look at the automobile industry. They announce 6-12 months ahead of time when a redesigned model is going to be released. Not only do they announce it, they show the new model at an auto show up to a year ahead of its release. Does that cause the sales of the current generation model to go to zero, no. This is a never ending cycle in the auto industry and many others as car companies do a total redesign of a model approximately every 5 years with two facelifts, usually, in between.
The Centrotec set has been asked about many times for many months. It would not be replacing a current set. North America has not had a set for a long time. Why hasn't anything been announced, even if they announce that its a year off.
