According to a "valued source" of eBookNewser, that plan would be in the next 60 days for those who pre-ordered the Kno already. Or at least "some" of the pre-orders as the first shipment will be to a "limited number of students and teachers."
There hasn't been a reason given for the delay, so you can take your pick among anything ranging from technical delays to lack of interest in the product. Given that most of these tablets made by under-the-radar suffer a long series of shipping setbacks and the Kno has only been through two, I'd guess a few more delays in the future are likely.
