It’ll definitely end on Act 7. 7 acts has always been the plan. It has been stated, just not directly
In [S] Seer: Descend, you walk down a hallway through 4 red curtain (Acts 1-4), A blue curtain (A5A1), then another red one (A5A2), onto a beat mesa like structure and take a teleporter (the scratch), and down another hallway through 6 green curtains (A6A1-A6A6) and then onto a platform with a skaia pattern, where you get a Frog statue (beating the game/Act 7)
