I investigated a bit these days, and it seems that effectively there are three versions:
Theatrical cut (available on BD, 2.35:1)
Extended Edition (available on LD, 1.90:1)
Special Edition (available on DVD, 1:85:1)
(any correction are welcome!)
So, at least, there are no Extended or Special Edition available on Blu Ray... yet!
Yes, I agree that the best option is the thetrical cut, but the EE has its right to be preserved, don't you think?
