Barnes & Noble released their new premium tablet e-reader - it is essentially the second generation Samsung Tab S 8.4 but with Nook e-services (apps, e-book shop and e-reading experience) built into the firmware. Barnes & Noble's dedicated hardware endured heavy loses, when going against Amazon's range of Kindle tablets, that necessitated a turn in direction. However, instead of concentrating on improving their e-ink reader and developing more choice beyond the Nook Glowlight, Barnes & Noble thought it would be better to release vanilla Samsung tablets with some add-ons. The question then is why add a premium device, that sells for $399, when no similarly priced device was released before, whether as a Nook tablet or in partnership with Samsung. If the current range of Tab 4 tablets is to be replaced, then a partnership with Asus for an eight inch tablet (Asus Zenpad 8) and Lenovo (Tab 2 A10) for a larger one, would offer good specifications at a more value friendly price.
My personal speculation is that the move to introduce an eight inch premium device, one with an excellent Amoled display, might be understood considering an earlier decision to partner with Samsung and purchase a stock of Tab 4 tablets. It is likely this is an attempt to add another option to the existing range of tablets with the Nook e-reading experience, beyond the more budget range on offer with the Tab 4 7 and 10.1. There is also, considering continuous loss, a large inventory of unsold Tab 4 tablets and it may not be workable to introduce a new range of partnered Nook tablets with other manufacturers. The Tab S2 could then be envisaged as a Nook offering with the existing Tab 4 range. Of course, the bigger problem was an attempt to offer some form of Nook device, even if it is nothing more than a Samsung tablet with some extra Nook features. When the Tab 5 is eventually released, as Samsung does continuously refresh its tablet line, then Barnes & Noble might need to significantly discount the Tab 4 range, as happened with the Nook HD and HD+ tablets, with a probable inventory of unsold device that need to be offloaded. Considering this, Barnes & Noble might decide to discontinue the Tab series partnership with Samsung, with one premium tablet being the only option to keep some form of Nook tablet. Going into partnership with another manufacturer could no longer be an option; however, this is Barnes & Noble, so it is difficult to predict or even understand what it decides next.
It should be stated that tablet sales are on the decline, other than Amazon dominating tablets with an e-reader focus; hence Kobo, I believe, has taken the right path in discontinuing their tablet range and working on offering a wider range of good e-readers (when Kobo announced a 300 ppi Kobo Glo HD, Amazon followed straight after by unexpectedly bumping up the resolution of their excellent Kindle Paperwhite). The point is that varying the range of e-ink readers is the only viable path to maintain the Nook platform beyond third-party apps. Considering this, it makes better sense if Barnes & Noble revamped their out-dated e-reader firmware and offered better options beyond their only dedicated e-reader (Nook Glowlight). May be offer a 9 inch e-reader and another budget six inch one, similar to the Nook Simple Touch. However, we can predict, considering the trajectory of the Nook platform, that nothing will be heeded from Kobo and what will be made available is another standard six inch reader successor to the Nook Glowlight, barely keeping up with what is being offered by Amazon and Kobo, along with the Tab S2.
