2. A 9 boss raid would have a life span of about 4.5 months, which would mean that without a filler raid, Argus would be released right in the Christmas period, which would be catastrophic for participation numbers.
3. A filler raid over the Christmas period would give Blizzard time to release the big Argus raid after the new year and maximise participation and retention.
In summary, I am anticipating a 3-4 boss filler raid after ToS to tie us over the new year before Argus is released.
