I actually didn't get the newsletter today. I got it on the 15/10/14. Also not sure about newsletter - I have a theory that the nintendo newsletter could potentially be tailored according to your purchase history and registration of games on Club Nintendo potentially affecting the promotions you get.
Though I'm not really sure whether it was a newsletter - it was an email titled "Special Gift For You - Pokémon Omega Ruby & Pokémon Alpha Sapphire Special Demo!"
