Actually, there are plans to go to print, as far as I know. Their contract stipulates print rights, not just e-rights, and Christine has discussed it on the author loop as well. She specifically mentioned everything over a certain word or page count would be elgible for print. (I paid attention to that bit because it looks like my book with them will be my first officially printed and not just published online).

I haven't seen any indication that her plans have changed.
