Someone at DPReview suggested that such tests are encouraged by Ricoh. This would explain why there are at least 3 such tests (and who knows how many more I haven't seen).
I'm a bit concerned about the lens mount (is it still fixed in polycarbonate, or metal?), but those are preproduction models, i.e. not for sale.

Well... it's a matter of preference and workflow. For you a side-articulated LCD might be better, even significantly so. But me, I'd mostly want to tilt the screen up/down for brief periods, and such a maneuver is unnecessarily complex with a side-articulated LCD - yet very easy with this system (or the 645Z's).
