The San Diego Comic Con event is happening right now and Square Enix has shared images of prototype toys for new Play Arts Kai figures. Many of the upcoming figures are for classic Final Fantasy characters.
A user on NeoGAF kindly posted images of the toys that are coming soon. Some are early prototypes which is why they are not colored in yet. Lightning is the best looking toy of the bunch.
Aside from Lighting, other toys include Zack Cid from FFVII, Cloud on his bike, Bahamut, Odin and even 2B from Nier: Automata. If you are a toy collector, these should be on your radar.
Exact pricing and release dates should be coming at a later date. Play Arts Kai is usually a high quality product as I’ve bought several Final Fantasy toys in the past and they are great.
