Just looking at the 40k codex page on the GW website...
Some are £17.50, some are £12...
And previously the Dark Eldar one was £12 before the new release, and weren't the DH and WH codexes £12 before they were made pdf-for-free?
So would I be correct in thinking those that are £17.50 aren't going to be changed? and that the £12 ones are next for update?
Which would leave Necrons, SoB, Tau and Black Templars... which could fit in to the Imperial/Xenos/Imperial etc pattern?
How far of the mark is the idle speculation likely to be?
