Love em!!
I quite enjoy how they can come up with a lot of different creatures given the same shape in altmode - a Teardrop shape for the cons and Pachinko shape for the autos...the lack of articulation at first bothered me but I've learned to accept it. Love the accessories each figure comes with. Ive been trying to google the combined mode for all the accessories. I read somewhere that it does combine into another minicon of sorts...but can't find it again 
Apparently Parramatta TRU has em out now (as per fatbot) right after I bought mine online coz I was not quite sure we'd ever get them, sigh
. I have the first four in hand, the second 4, I had purchased for me by my friend overseas ( Philippines) as it has been out on local retail there for about 2 months now. So all secured for me but I'll be getting those by next year when I go for holidays...
As for creatures to come up with, hmmm a crab, a different dragon (for the Pachinko shape) a bear, a beetle of sorts, a spider, and a quadruped dino, wouldn't hurt for a pterosaur too..
Now some pics - my fave so far is Dragonus
