Cheers for the responses, sounds good

I’ll try and aim to go to Britcon I think and perhaps others sooner too depending how soon I get my army done.
Does anyone have links to pictures of previous armies that have won best army prizes at all, so I could have some idea what the standard can be like? And it's always nice to see pretty armies.
The army I’m working on at the moment will work fine with the standard list. The Saim-han I just have in mind as a possible choice for the army after that and oddly might be a bit more problematic, but it's ages off anyway and I may well do a differeng army before them. The issue with them is just I want to go all out for speed with all bikes and falcon varients and no foot troops. The only way to do that in Biel-tan would be to count all the jetbike units as shining spears, which feels a bit wrong somehow. Though at least I could still use them that way though, do feel sorry for the poor Tau and Tyranid players who I believe can't join the fun at all.
Are there any plans to make other lists tournament official in future? It might be nice to have a bit more variety, though they'd need to be well put together and balanced.
