Now, now, there's no good reason to drive
this thread into the Soap Box.
That is a real good intention.
So what - about Ektrachrome ? There is a plan to bring back sheet films. The 4 x 5 format is for sure.
The 8 x 10 format is planned but the question is from demand.
The possible 5 x 7 format is not in plan - but this may change.
So if there is a real demand on 8 x 10 ( nowbody knows at this time ) there may be a door wich can be opend to proceed with 5 x 7 - what is a real nice format from my point.
The aceptance on Ektachrome 8 x 10 is dependable from the pricing....

....?
If you are looking to Fuji E6 one may come to the conclusion that 8x10 is out oft interist for most
photographers. A lot of them who used color film in higher formats proceed meanwhile with bw.
What is definitifly caused from high pricing because the interest to color film special to E6 is still there what we can see with the extraordinary demand on Ektachrome 35mm since last year!
But there will be an official statement on this issue within this year

(for some oft your guys who
just still belive on the bringing back of Ektachrome 100 in 120, 4x5 inch, [ 8x10 inch ?] at that point
when they will hold this formats in their own hands.
