There seems to be very little discussion about the 2015 Fire HD lineup here, only 5 weeks after shipping.

As a point of reference, consider the number of reviews for these on Amazon.com (assumption: reviews correlate strongly with unit sales):

Fire 7: 12,009
Fire HD8: 1,788
Fire HD10: 1,355
Fire HD6: about 680 reviews since new tablets shipped

As another point of reference, consider analogous numbers for the Kindle lineup:

Kindle: 12,665 (about 3,330 since PW3 shipped, about 680 since Fire HDs shipped)
Kindle Paperwhite 3 (shipped end of June 2015, about 2300 since Fire HDs shipped): 8,805
Kindle Voyage: 7,500 (about 1,800 since PW3 shipped, about 400 since Fire HDs shipped)

So some trends are clear:

- Cheap tablets are popular. HD7 represents 70% of Fire sales.
- The Kindle Voyage accounts for about about 12% of Kindle sales, but less than 2% of device sales.
- Fire devices account for about 80% of Amazon device sales since the new Fire HD lineup launched.

This makes prospect of future premium devices like HDX and Voyage seem unlikely. Amazon will not make new devices if they don't sell in sufficient quantities to recoup startup costs in a reasonable amount of time.
