Yes of course there will be books, and their 'type' will the the same type that has always been in TES games, also what exactly were these staples of TES games that have been thrown out the window ?
I would have said two weeks ago that "Yes of course it will have first/third-person real-time action combat like (or improved upon) Skyrim, it's a TES game!" Careful what you wish for, I'm not holding my breath any more. Anyway, as far as the myriad of other mechanics missing (aiming bows, spells, real-time melee, first-person view, art-style/aesthetics, Imperials, warring factions that don't rely on race, player housing, etc.) those things can be found talked about (by me in particular) in many other threads. Not really the topic for discussion here.
As far as the writing of the books is concerned. 250 devs, 5 years. If at least 5 of them weren't dedicated to writing more books at some point, then this developer truly does not understand what makes TES special. As Todd Howard says, the spirit of TES is in the details, not the broad strokes.
