Do all hardcover books eventually get published in mass-market paperback?

[Stéphanie]

I was wondering if anyone knows if all books that are published in hardcover first eventually get published into mass market paperback? I know they usually get put into trade paperback but wasn't sure about mass market paperback which is the smallest, cheapest style they usually sell of a book. I had just recently bought The Girl With The Dragon Tattoo and The Girl Who Played With Fire in mass paperback style. I know there is a 3rd book to the series that comes out in May that will come out as hardcover. I want to eventually buy it in mass market paperbook. I know this will be quite awhile before it goes to paperback. I have no problem waiting to buy it. I just like all my books to look the same in a series (all paperback or all hardcover).
