According to the way Tomino has done things before and other Gundam fans and sources I've dealt with the later production will take precendence. Hence why so many people got curious about why his helmet was removed the first time the movies were aired. That was part of the begging for discussions that they were gonna be making a seed 2 at the time. Atleast making an OVA for after SEED where Mwu would return. Instead the rumor turned out to be true we got a SEED 2 but not an OVA we have gotten Destiny and now the supposed return of Mwu. While its not official that its Mwu things are looking that way more and more. Again Terra you can say its not Mwu and I can say it most likely is. But the way things keep going its gonna be so.
