I found out on GrooveBricks that there may be at least three new sets coming in the summer of 2015. They are:
- 70171 Ultrasonic Showdown
- 70172 AntiMatter's Portal Hideout
- 70173 Ultra Agents Ocean HQ
This wave may bring more buildings. AntiMatter would be the second Super Villain to appear in two waves, the first being Toxikita. Also, 70173 Ultra Agents Ocean HQ would be the second water mission, the first being 70160 Riverside Raid.
Which minifigures do you think will appear in each set? AntiMatter is assumed for 70162 AntiMatter's Portal Hideout.
