I voted for the Western Heartlands, which to my knowledge *hasn't* really been covered, even in 2e (other than Volo's Guide to the Sword Coast).
It has. The Western Heartlands have been extensively covered in the FRCS, Volo's Guide to the Sword Coast, and the 2e Campaign Setting, among others. These books have multiple sections and paragraphs covering every named area within the Western Heartlands.
While I'm at it (when I mention FRCS, it means that the FRCS gives a good deal of coverage to that area, compared to other areas like Nimbral and Lantan):
Cormyr - FRCS, Cormyr Accessory, Volo's Guide to Cormyr, 2e Campaign Setting.
Dalelands - FRCS, Dalelands Accessory, Volo's Guide to the Dalelands, 2e Campaign Setting.
Waterdeep - FR1 Waterdeep and the North, City System box, Volo's Guide to Waterdeep, City of Splendors.
The North - FR5 Savage Frontier, Volo's Guide to the North, The North box, Silver Marches.
I would like other areas of Faerun (the untouched areas) detailed before any of the ones I mentioned above are regurgitated again, since they have been done to death. After those areas have been detailed, *then* I would be fine with returning to those areas, as a somewhat reasonable amount of time has passed to make regurgitation products semi-worthwhile.
Will this happen? Knowing WotC - heck no. Regurgitation products can be produced cheaply, since a large amount of work can be hacked out by R&D and the product will still sell anyways because of the "FR" logo.
Ah, the life of a FR DM.
