The fact that they're selling on Premium Bandai is simply to get bigger direct profits. They saw how successful the V-Pets are and put them on their own site in bundles so that you'd have to spend at least $60 for them.
Don't be surprised if the X series ends up P-Bandai exclusive if the Wave 3 sells well.
