The movie hadn't 'happened' the last time Unicron made an appearance either, so I would support the 'could be popular this time around' view. That, and I didn't get one before, so I'm definitely getting one this time around

I bet the initial price point will be painful though, at least until sale time comes around. I'm getting visions of Unicron in planet mode inhaling and devouring the wallets of the toy collecting citizens of earth (shortly before making his home in their living rooms... )
