All were already known unfortunately. Which is a shame, because it spoils the fun of having at least something revealed as a surprise at the convention. I think the last two years at least had one toy not leaked before the convention (the attendee freebie figures I think), but not this year.
So getting over the rant, the rumour is true, there are 3 sets this year.

Set 1 - Sweep 2, Sweep 6, Sweep7. (3-pack)
Set 2 - Elita 1, Razorclaw.
Set 3 - Banzai-tron, Skyquake.

Which leaves the freebie figure for pre-reg attendees being Leozak.

No prices or pics yet, they will be known tomorrow.
