Is DC Comics' New 52 Temporary?

When DC Comics revealed their 'reboot', I thought it will last about a year tops and go back to normal. Some of my fellow geeks laughed at me.

Now, they are possibly looking at my idea again. On some of the comic blogs, this panel from the Justice League No. 6 popped up. The reason is very clear, it may have revealed that this reboot is a temporary thing, see here.

This Pandora woman rewrote reality? So does this mean that the DC universe we know may be back? I don't know, but this is a great way to keep readers on their toes and buying DC comics.
