Yes. If you mean Microsoft Dynamics 365 / Power Platform Release Wave 2 2026, Microsoft has not yet published the full 2026 release wave 2 plans as of August 24, 2026.
Microsoft's release cadence gives a useful indication:
Wave 1: April–September
Wave 2: October–March
Microsoft generally publishes the next wave's plans before the wave starts, rather than waiting until October.
Microsoft says release plans are updated weekly as feature information becomes available.
