According to O'Reilly's page (linked from Microsoft's page as the book supplier), the book is now not estimated to be available until July 2014: http://shop.oreilly.com/product/0790145370839.do
I was suckered in by the exam voucher pack, back when the estimated ship date was November. While I recognize that there are other materials available, there are no Microsoft endorsed exam prep books available for this test.
For anyone planning on pursuing the MCSE, I recommend that you wait. If you buy an exam pack with the expectation to use this material, your vouchers will expire before material becomes available.
This is really disappointing if this has been delayed yet again
