Question about lessons

Dear Chinesepod Staff

I have a question I'd like to ask. 

I was reading through one of the discussion boards from a recent lesson, and Catherinm wrote in one of her comments that you guys aren't making any new Newbie lessons. Then I went browsing through the Lessons page and  I noticed that there were 326 newbie lessons when you guys stopped making making them, and that there are now more elementary lessons (346) , and almost as many intermediate lessons (305).

My question is, how much longer do you predict you will go , with making new elementary and intermediate lessons, before you guys decide to stop making those as well ? And if you decide to stop making lessons in one or both of those levels, what will you make instead ?
