Pro ASP.NET MVC 2 Framework was just released by Apress and I should have my copy by the middle of next week. I am really looking forward to the second edition of this book as I found the first edition excellent ( Pro ASP.NET MVC Framework Book Review ).
You can expect a review of the book within a week or two :)
Although a bit dated now that we should be seeing updated versions of MVC Books for ASP.NET MVC 2, you can also check out my thoughts on choosing a book on the ASP.NET MVC Framework.
