Could be windshileld. Could be upper top corners of drip rails where they meet a-pillars. Could be front roof rail attachment points (foam seals start to become waterlogged and leak). And obviously the sunroof.
When my front roof rail attachment points were leaking, I got drops right where you circled, above the windshield. The roof has 2 skins (inner and outer) and when those roof rail attachments were leaking, they leaked between the roof skins, and it made its way dead center of windshield. At that point, there's a gap between the welds on the roof skins so water that gets trapped in there can come out.
I find when sunroof leaks though, it comes out everywhere at the sides. The location of your drips suggests to me something is getting between the roof skins.
BTW fix this as soon as you can because it'll cause corrosion on your fusebox (under drivers dash area) and on your ECU's / wiring (passenger footwell), in addition to the obvious floor rust issues over time.
