The next release for the 5th edition files is due out soon. This will be a bugfix release for the Space Marines and hopefully, cross fingers, include the SM AP units back in as well.
What won't be included in this release will be the Deathwatch - it is for reasons of timescales and a few other issues too - be patient though as they will be back!! We know they won't be in there so please don't post endless bugreports telling us about it.
After this release is out then we are looking to put some of the fancy things into the 5th edition files as well as gettin the Imperial Armour stuff up to date too.
Enjoy
