@Miguel Evaristo 14 if you include No Good Deed. The F4 reboot was confirmed to be a part of the X-Universe in 2013 when it was in pre-production. When the film released and its bad reception, both critically and commercially, Fox, Trank and Kinberg renounced their initial statement and said it was set within its own universe. Two years later, Fox was planning to integrate the reboot F4 into DP2 and all was done and ready to go but was scrapped at the last minute due to financial restrictions.
As for the original F4 movies, its just a theory on my part.
As bad as the reboot was, FAN4STIC is officially canon to the X-Universe.
