That suggestion is pure conjecture bordering on delusion, but it's partly as a result of SE not being more open to share information for certain content like BLU, Ocean Fishing and Gold Saucer. We usually don't hear anything about these topics besides the random "Hey! It's getting randomly updated this coming patch!", but I digress.
When it comes to BLU, the only "plan" I recall is when Yoshi-P mentioned during an interview pre-ShB of BLU receiving 128 spells followed by (constructive) feedback for the concept. Looks like they'll hit the 128 mark with the level 80 update. So we'll have to wait and see, I guess.
