That was my first thought. Did somebody mix up the heads to the bodies? They're wearing the wrong outfits!
Aha, but no they're not. This is the "Regeneration Collection" - and with the obvious exception of #1, they're all wearing the previous Doctor's outfit that they died and regenerated in. Perhaps mirroring the impossibility of tracking him down for reunion specials, Christopher Eccleston's #9 is a chase figure - one of four (I would assume the War Doctor to be one of the remaining three, and maybe Tom Baker's future Curator as another).
Why is #4 the only one who looks happy?
