The title is "Gundam vs Alien" ("ガンダム vs 宇宙人") ^^
The article also mentioned the meaning the "ELS" as revealed in the latest trailer last Wednesday. It's "Extraterrestrial Livingmetal Shapeshifter" (地球外変異性金属体), which is something many fans have been talking about. The large bit-like object as seen in the trailer is also confirmed to be an ELS, whatever it's supposed to do.
The movie will be released on September 18th.
