Clarification Request: EF - EFD - FitS

[Dan Storm]

Good Afternoon All;

Still gathering information about all the modules and upcoming releases so I can make my own wishlist and I was hoping the gang could help me.

Can you please let me know what the differences are between "Eastern Front" and "Eastern Front Deluxe" and the new "Fire in the Steppe"?

From what I can gather:
All 3 have Boards 1 - 8 - with FitS having updated artwork.
All 3 use the same 660 pieces.

EF and EFD have 112 scenarios.
FitS has 60 Scenarios - none of which are duplicates from the original 112.

EF / EFD - I have found pictures of 2 different covers - Tiger Tank / Horses.

Is FitS a Version 3 of EF?
Do all 3 games cover the same topic?

Thanks in advance for the assist!

Dan
