How "limited" are these?
In following the release of these over at MTG Salvation is seems like, at least in the US, anybody that ordered them received a good amount of them. The local store got close to 20 of them in and they're small potatoes in the grand scheme of things. I've read of stores jacking the prices way up (between $60-$100 instead of MSRP $35) and limiting purchases to one per person but overall I get the feeling they a lot more prevalent than FTV: Dragons from a year ago.
I heard that they were more rare than the FTV dragons, but as you noted there doesn't seem to be much of a supply issue.
