Does anyone know when Wrox professional java 7th edition is coming out (if its within a few more months ill wait)?

Im looking for a book to learn more java. I do android dev and i have read and done the examples in "Java 24 Hours". I know how to build GUIs and interfaces, work with sql databases, read and write data, and do basic threading and error handling but i want to learn more. Any good books?

Thanks,
Adam
