Well the lack of "grip" is a strong hint for CA anyway. Even if the bricks are
not warped, there is some extent of shrinkage which causes the lack of grip - I
think I heard from different sources that CA bricks never had too much grip to
begin with.

Could be - I can only refer to the few blue slopes I have, and the material is
positively ABS. Might be LEGO produced ABS bricks using the old masters,
although I understand the machinery required is in several points very different
from the one used for CA.
Isn't there any official statement on the history of LEGO brick materials?
