Yes, some people managed to get a few very rare or unusual keycaps - but that was the exception.
The vast majority of keycaps were multiple, multiple copies of partial sets of white on black DS IIRC.
You poopin on my party over here? I'm tryin to hype for crap bags.
Oh, they'll sell. Don't you worry about that.
Sold out quite quickly last time.
I was tempted, but the postage price to Australia for the relatively small chance of getting a few useful keycaps was too high, so I skipped it.
It was great when people got theirs though, someone posted a video of himself sorting the keycaps in real time - that was fun
