The quoted article refers to an Allpar web page that predates the Las Vegas show Wrangler-reveal to dealers by a few days (compare the "last updated" box to the show dates). That Allpar page is a Franken-mix of info spliced from various sources over a long period of time. They got lazy I guess and stopped updating that specific page on Aug 24. The info below IS in other places on their site/forums, though.
The dealers interviewed after SEEING IT didn't say the soft top would stay in its current form, only that there would still be a soft top option. It could be that a soft top panel systems fits that description, though I doubt the substructure will be visible in between the panels (like the B-pillar is now visible between the doors). The half doors remain an option, which means if the soft top is moving to a panel system, then the half door uppers must be stiff panels, too, which will at least kill the buffeting and may allow for a sliding hard window. I'm going to go out on a limb and say there may be stiff panels on the sides but the top will still fold back somehow. It will probably be (as has already been stated) very much like the new Bestop Trektop Pro - after all, Bestop manufacturers the current soft tops for Jeep, so it only makes sense the Pro is telling us something about what's coming on the JL. Regarding the windshield: the report after the Vegas show was the folding windshield stays, but it has been redesigned.
But let's not forget the best bit of information about the JL from the dealers that saw it - it will have a smaller but VERTICAL grill like the TJ. I'm guessing the smaller grill means a more narrow front with swooping quarter panels for better aerodynamics.
