I LOVE how that they have that '2 in 1' sticker on there. What part of the word 'Transformer' do U not get?? I'm sorry if I come across as being a bastard, I've just had a bad day today.
WHAAAAAAAAAAAAAAAAAAAATTTT??????????? Dude, there should totally be a fan-dom for stuff like that ;}!
A little backstory on the "2 in 1". It's actually been a mainstay of European Transformers since around about 2005 or earlier. It's like Orio says, it is to indicate the "two toys in one" thing. I share your bemusement at just why our Transformers needed this pointing out (especially with the 12 languages proclaiming "robot becomes attack helicopter" on the back of the packaging). I guess perhaps it really is there to emphasise this fact. Maybe your average Joe in the street doesn't "get it" so readily, or maybe the big "two in one robot to vehicle" just gets more attention?
Got myself one (from Ebay, he's not at the UK yet). Check out the gallery [/shameless plug] Soundwave - Cyberverse - TFW2005.COM
