They’ve done a pretty good job of keeping them hidden, though from all indications, the only exterior indications of a 2020 appear to be the TSS equipment behind the logo (or the plastic panel on the Pro) and windshield. They could be testing them in plain sight and most people wouldn’t notice.

I’m hoping LED lighting and Blind Spot Monitoring appear, but also know realistically 1) they probably would have mentioned it in the TRD Pro auto show reveal (I mean, 2 additional USB ports made the cut for the press release, so seems like they were reaching for something, anything, to talk about) and 2) no reason why they would add them to the lower trims and not the TRD Pro.
