3. NEXT-RELEASE FORECAST & PLAIN-LANGUAGE METHOD
How We Estimate the Next Meta Release Window
Plain-language method: We take the last 4 public release gaps for Meta:
The shortest of those 4 gaps is 3 days, the median is 14 days, and the longest is 40 days. Adding those intervals to Muse Spark Open (2026-10-15) places the historical cadence window between 2026-10-18 and 2026-11-24 (median date: 2026-10-29). Rough estimate from 4 gaps ranging 3 to 40 days. Labs do not follow schedules.
