>>7532376Shizuoka Hobby Show did say "Next Phase Coming Soon" below the platform of the ace armour and design sketch display. On the 2nd day they moved the latter 3 colour schemes of the samples away from the announced ones that are due in June/July.
I think wave 2 will be the latter 3 colours plus ace armour and high mobility parts. They will most likely be shown at Chara Hobby in August and slated for release in December/Jan.
Low res pic is from day 1 showing the Gray Alto with gray sniper armour. The latter 3 colours don't have release dates but do have the same price listed.
Video from YouTube at 14:50 is from day 2, showing off the runners of the armour parts and weapons set.
