The Shine bright line tends to have light-up horns/wings. It is currently on the same chinese website as the Canterlot Castle and random recolor ponies
Those guys must have some pony hacks rolling or something on Hasbro's marketing department servers, they beat everyone to the punch!
Anyway thanks to everyone who told me about these!
Now to just wait for those high quality molded cast ponies... you can do it Hasbro! I have faith! Twilight Sparkle and Trixie are worth it!
