Oxford University Press (USA) has produced a King James Bible for the 400th anniversary next year. It is a Roman text reprint of the original 1611. They have left in any errors, spellings and special features of the original. The "Translators to the Reader" and other preliminary material are there as well. At the back, an "errata" page shows some of the misspellings of the original.
It looks similar to the one Hendrickson did in 2003, though the Oxford Bible is 9.1" x 11.3" - much larger. It is available on Amazon.com and most likely many other sellers as well.
I first heard about this new Bible from Gconan, on the Bible Versions Discussion Board. He frequently catches new Bibles as they come out.
