Obviously it's not an official sequel because Itoi stated in an interview that he was no longer going to work on the Mother series, but it seems like a pretty cool idea.
Sorry for the blatantly late reply. But yes, you are right. This isn't an official sequel, but a fan game being made by a development team of die-hard fans of the Earthbound franchise. It's not in any way funded, endorsed, or acknowledged by Nintendo, Brownie Brown, Ape/Creatures Inc, or HAL Laboratory. It won't be canon to the official storyline that's set by Nintendo or Shigesato Itoi. Itoi himself said that he'd much rather play the next Mother game than make it.
However, hopefully the folks at Nintendo and perhaps Itoi will appreciate the effort and maybe it'll inspire the big guy to continue this awesome, yet heartbreaking-ass series.
