Not all of them, I might open some more Commemoratives soon to display around Ultimate Bumblebee (Jazz and Hoist, can't convince myself to open the others!)

I'll open them if I feel like it, but I like keeping them new. I like the Voyager 25 anniversary boxes, with the G1-like artwork. Having said that, I'm not a big fan of the new ROTF packaging.

Stormcloud - Toyworld Balcatta was only $30 suprisingly for Ultra (none left now, was only 1)
Treadbolt - KMart Clarkson
Unicron - Ebay overseas seller rei_jinn from Singapore
