To be honest, until Volume 5 I fell into the camp that thought Bumblebee was a cute fan ship, but that there wasn't a lot of evidence of it being a real thing in RWBY. In fact, I'd go so far as to call almost all the arguments serious over-reach.
However... in Volume 5 there were conversational hints that both Blake and Yang were more strongly bonded than had previously been obvious, and that other characters had noticed this. Even then, it could've been just because they were very close friends, but you could at least argue that they were foreshadowing Bumblebee in the future.
And Volume 6 pretty much sealed it for me. Yes, girls can hold hands in a platonic fashion. But looking through RWBY, there isn't a lot of platonic hand-holding going on. Ruby and Penny is the only example I think of. In fact, it's pretty clear that Yang and Blake hold hands more often than all the other characters combined. Furthermore, the look over the shoulder that Blake gives Yang in Episode 10 is pretty blatant. I certainly know what I'd be thinking if a girl looked at me that way.
So even though Bumblebee isn't confirmed, I'm pretty convinced that CRWBY are going to run with it.
So, having come to that conclusion, you can now look back at Volumes 1 to 5, and suddenly a lot of the stuff that was weak evidence of Bumblebee at the time now looks like foreshadowing. And that was probably CRWBY's intent. It seems likely now that CRWBY had Bumblebee in mind as a possibility from fairly early in the show.
But that's in hindsight. :)
