For now, there are no changes to the
LW (44-45) or
EW (39-41) lists, so you are still good with the books you have. The rulebook you bought is *only* for the new
MW lists that they have released (
DAK and Desert Rats and others to come). To play
LW or
EW you need to get ahold of the free
EW/
LW rulebook, and the free book to adapt the
EW/
LW lists to v4. They were giving these away to anyone with a copy of the old v3 rulebook, but I'm not sure if they are still available. You can still download the two books from the
FOW website:

There are no cards for
EW/
LW as of now, and the point values remain the same. There probably won't be any changes until they start revising the lists for those periods to be fully v4 compliant like the new
MW lists. This probably won't happen for at least a year, maybe two, (until they finish
MW North Africa and Eastern Front) so you have plenty of time to game using the lists you have. I think the old tokens should still work, they came out with new ones for the
MW Brits and Germans, but they are mostly the same.
