I think that in general the Java EE has been moving faster from Java EE 6. Java EE 7 was release past year and now the JSR for Java EE 8 are starting to move.
So we can estimate that Java EE 8 is just around the corner (maybe by 2016).
Do you have any strategy or actual date of when is going to be OCMJEA for Java EE 7?
Regards, and thank you for your effort on writing this book. I was looking forward to see it coming on this month.
