I picked up the Boarding Action terrain box a few weeks ago and am having my first game on Saturday. I'm going through the main rules and mustering rules so I can teach my buddy who plays Tau and I'm wondering if GW has said anything about IF they'll update BAs after new codices have been released.

For example Farsight would obviously still lose Deepstrike but I'm assuming he'd keep his other abilities from the new codex?

Or if my buddy wants to bring one of the new shaper types with his Kroot instead of the standard one what abilities would be allowed and what wouldn't.

I almost feel like they're going to focus on 10th first and then MAYBE touch up BAs
