Those who predicted prime tended to be more guarded about their prediction, knowing it could go either way. Most of the predictions that this would be in the JJ-Verse continuity, however, didn't phrase it as a guess. They put it forward as a fact and anyone who disagreed would get a flippant Cumbernope. The attitude was that Prime was played out and anyone who thought otherwise were out-of-touch purists who should just go sit in the corner and leave the Trek franchise for the next generation of fans raised on nuTrek. So I think those people should indeed eat humble-pie.
And the irony here is that if it had turned out that the new show was set in the Abramsverse, I doubt we would have heard a peep out of the OP. Instead we get offered an inane retort of "BOW DOWN AND BE HUMBLE AT MY FEET, FOR I HAVE THE AWESOME POWER OF BEING ABLE TO PREDICT THE FUTURE BY MAKING A GUESS THAT HAS A 50% CHANCE OF BEING RIGHT!"
So that humble pie can be stuck where the sun doesn't shine.
