How come BB8 is still not here?

It's been over 4 months since BB8's first appearance. I won't count the second coming because it was only for Rey and when R2 came back for CLS, he still returned on schedule. Since BB8 came first in late September it's actually quite long since then.

I know this is a dark side month but that doesn't mean we have to suffer in haat for another month, besides it would have no effect on dark side content.
