Then, having had some interaction with a couple of thousand realtors over the years, and knowing many of them fairly well, expressed the thought that it was unlikely that any agent could stop the urge to share a rendering if they had one available....
Again, terribly sorry, having only had experience on the construction side of things where we routinely have access to confidential materials and somehow manage to respect our non-disclosure agreements it seemed unfathomable to think that anyone else involved in the process could be so unprofessional and disrespectful as to submit to their base desire for commissions and reveal information not yet approved for dissemination. But you clearly know realtors far better than anyone else on the board, and perhaps you're right about their character and underlying motivations.
Or, maybe as suggested, there's a single brokerage quietly handling sales to preferred clients who are buying primarily as investments. I'm not a realtor, I certainly haven't been in real estate for longer than I've been alive, and I have the business cards of several thousand fewer realtors than you do, but even I know that not all people who buy real estate are college kids looking for a bachelor pad with a fancy glass lobby and a clever marketing scheme. These are expensive units, and at this stage they're probably being marketed as assets, not homes or lifestyles. To be worthwhile as an asset buyers only really need to know about square footage, carrying costs, and potential appreciation on their units.
I'd imagine people buying in at this stage are probably on agreements with liberal escape clauses, and they're likely getting prices even below pre-construction pricing to make up for the fact that floorplans and elevations are still subject to change depending on the tender process. And given that everything is subject to change, why would anyone bother releasing any information about the tentative plans?
But more to the point, my post was relevant because you're using the non-existence of a rendering to argue that sales likely aren't proceeding. I'm telling you there may or may not be a fancy CGI rendering and animated fly-bys of the building, but there are definitely preliminary sketches, certainly detailed enough to make some discreet phone calls to respected buyers. And the people involved right now are not going to be the desperate yokel realtors that are a dime-a-dozen-thousand, they're going to be preferred clients that are sensible enough to not broadcast to the world that they've been given front of the line access to the project, especially with the brouhaha that happened with X2 (and Aura... and the original 1BE...) with respect to line-ups.
