Ed Greenwood's Guide to the Dalelands just got its cover reveal and a delay to June. Is authentic Forgotten Realms content finally arriving or is this just more of WotC using nostalgia bait to cover up their ongoing shift away from Classic Gaming roots?

Realmsbound is helmed by Eric Menge, and is a collective of designers, writers, and artists who are all fans of the Realms (including former TSR staffers and longtime Realms novelists). Wizards has no direct involvement, and hasn't seen any draft material. I'm contributing lore.

Is this based during a particular timeframe?
