Well I have nothing against collecting TEST
cels, I am just saying that as only pre-
production items, there is no reason why they
would be so expensive.
Now about your analysis of the evolution of the
character design of the X manga, X², X - the
Movie, and X TV, it is right but the main reason
of the evolution (it's becoming simpler) is
definitely not the evolution of the style of the
animators. It's just a question of time and
money. The manga is not animated, so the
drawings can be more detailes. For X², a 2:35
show they had lots of money (I heard it was at
that time the most expensive/minute animated
music video). They had less money/minute for the
movie, and even less for the TV series.
