There is no "perfect" solution. If they string you along now, then they get slammed for leading people on when they announce something without a precisely correct release date. Let's assume that they say "here's what to expect from the Model 1071" today, give us a feature list, and then add that it's going to be released in Q4 2009 (I just made that date up, by the way), if they miss that date they will have potential customers who have planned their purchases around that product mad at them. They will then have those mad customers complaining until the product arrives.

History tells us that keeping things quiet until you have product very close to release is least likely to create grief. That's been true for Outlaw and a number of other manufacturers.
