First, Voxilla seems to be getting this information from somewhere on Obihai website; however, I can't find it. So, the question is whether it is there or not.
If not, then you may have a point - but one can also argue that most people on this forum are loyal Obihai customers who have in some cases more than one device and are considering buying or recommending more. Therefore knowing that a new model is coming in a week or month would generate necessary good will (look at Apple strategy of keeping the buzz going)
If, on the other hand, Obihai did make an announcement about new model than (a) both your and mine arguments are moot, and (b-1) obi website may need some UI improvement or (b-2) I need to have my eyes examined.
I also just noticed that somebody else decided that the best place to make a post about upcoming model is in Installation forum... maybe the device is already out and he is installing?
