All I could find so far is this (open) Sun bug/RFE entry with 426 506 votes:
http://bugs.sun.com/view_bug.do?bug_id=6530906
It's in third place in the list of RFEs.
Tons of people have stated that it will be included in Java 7...but does anyone have any clear information on whether MiGLayout will be included?

Well, it seems Chad has a point - it's not on any official list anywhere, and time is sure ticking away, so unless something big happens, it's safe to say MiGLayout apparently will not be included in Java 7, literally in spite of 426 votes from the community. Too bad.
I try to keep up on JDK 7 news (here's a good tumblr blog on it) and I actually hadn't heard about it. this post goes over some of the enhancements in JDK7 as of October 2009, and it doesn't mention MigLayout. Here's what it says on swing:
10. Swing updates There would be small additions to the Swing API including the JXLayer component decorator, JXDatePicker, and possibly CSS-based styling. JXLayer allows users to easily decorate the compound components and catch all Mouse, Keyboard and FocusEvent for all its subcomponents.
That was back in October. The biggest news on JDK7 is the Inclusion of closures. They were proposed but then dropped. But in November (after Oracle bought Sun) they got put back in. That pushed the deadline back to september of this year (it was going to be out this quarter)
here's a complete list of JDK7 featuers. I don't see MiGlayout anywhere.
I can't find it, therefore I don't think so. (Looking at a 30 day old version of JDK 1.7.0)
