According to @Lego_Minecraft_Goat, the three Spidey sets are:

11206 Spidey on his Motorcycle vs Rhino ($9.99)
11207 Spidey: Underwater Vehicles ($34.99)
11208 Team Spidey Pirate Ship ($59.99)
Fingers crossed for a handful of new character or variants! The sets will surely introduce a new tricorn piece for the three protagonists. While their hats will definitely not be useful for any other setting with those colour schemes and the logos, the piece itself might come in handy later!
