Came out today with the Troll Invasion, wasn't posted in the newspost or mentioned by Jagex on the forums, seems like they were trying to keep it quiet.

FAQ came out, pasted relevant part.
"Why were the vanity items not announced via a newspost?"
Mod Nexus: They were not officially announced as the promotion hasnt been launched yet. Watch this space!
"Why did you make vanity items only attainable through game cards? Will they be available via other methods of payment?"
Mod Nexus: The Katana is going to be used for a promotional period with game cards to begin with; and will be used for other offers in the future (including other payment methods).
"How long will the Katana offer be available for?"
Mod Nexus: The Katana can and will be used for future promotional offers, but they will not run 365 days of the year.
"Why do short-term game cards qualify for the katana, whereas loyal members that pay for year-long subscriptions get nothing?"
Mod Nexus: As mentioned above, other offers and promotions will become available. Also, dont forget about the upcoming Members Loyalty program!
"Is this the beginning of introducing micro transactions to the game?"
Mod Nexus: This isnt a micro transaction. You are paying for membership and a whole host of other benefits. A micro transaction would be give us $2 and well give you a cabbage (regardless of free or members).
Please note, a separate FAQ will be posted once the promotion has been launched (June 20th).
