Don't you think VSL might have *their* reasons for not revealing timetables or details ahead of time? Maybe those might be very valid reasons that they don't want to discuss for reasons of their own. I look at it this way - so far they have delivered, frankly if you think about it, products beyond our wildest dreams 15 years ago and then some - and it's worked out pretty good - so I am inclined very much to give them the well-deserved benefit of the doubt in this case. I can imagine the reasons why they might do this there are many. There is also another (among many others) company who tended to keep developments close to the chest and for good reason and that is Apple under Steve - and I always thought that was an incredibly smart way to play things and worked out well for that company as well whatever critics may say (and there will always be critics). The fact is that in the corporate world where you have unique strategies and technologies it's naive to think you can just be open about it and still remain commercially viable. There are no dobut real world considerations, as well like I mentioned, it just simplifies your relationship with your customer and that is a good thing - "this is what we have, when we have more, we'll tell you". There's no room for ambiguity, hurt feelings, disappointments, or delays that result in all kinds of anger. I'm just guessing at possible reasons, those two seem plausible enough to me to warrant their policy on their own, I'm sure there are plenty more I can't think of just now.
The proof is in the pudding. Know them by their fruits as the saying goes: Does VSL care about it's customers? Have you tried their products? Incredibly complex libraries and software that *works*. I say VSL cares very much about it's customers that's based on a decade of experience and observation.
