Perhaps the same reason there was never one for LGD5?

I assume there will be one in the near future though.

The last RPG contest ended with the lowest amount of entries so far so they made a news entry about it this early.

The BBC contests get much more attention because the BBC forum is more popular and because of the amount of entries they get, the forum is filled with banners for MOC's in the contest.

It won't be long before the BBC contest gets a news entry though.
