I haven't seen anything aside from the general site plan. I'm not actually sure which tower would be built next, although judging by the map here (via nj.com)
I'd think the next one would be the one directly west of the current VYV/VYV 2 as it would require no building demolition. I suppose the same could be said of the building(s) south of it, but that would probably affect the loading docks and truck movement for the current stores.
I only hope they change the design and some of the heights of the later towers - 10 more of these would be pretty ugly.
