While the dragons look great, I'm most excited for the first place trophy- it would look great with the Perfect Paradise trophy. Once I have the two, my island's symmetry will be complete, and I won't have to bother with trophies!
Here's hoping we get a nice habitat and some cool dragons from the milestone. I'm really hoping it isn't just all the dragons from that Steller event from a few years ago, or whatever it was called.
