I'm glad this has come up because it's reminded me about something that came up this weekend that WILL cause a revision to be made as far as fortifications and out tournaments are concerned.
To answer your question directly, we DO plan to allow the new fortifications in our events (except for the Apocalypse thing, I forget what it's called). So the fortifications that aren't allowed will be: Fortress of Redemption, new Apoc thing, and sometimes the Skyshield Landing Pad.
The change that will be made for upcoming event posts will look something like: If you take a fortification you are doing so under the the agreement that it will be played as if it were modeled like the default version. Any and all judgement calls made by a referee will treat your fortification as if it were GW stock. Modeling for advantage will not be allowed or accepted.
4 heavy bolters on the front side of your bastion, regardless of what the rules may suggest, will not be allowed.
Also, just so I can post it up where some people might read it: When you're submitting your army to be judged for appearance, it's straight up
cheating to include (or not include) ANYTHING other than exactly what is in your list. If you do that, stop doing it.
