I was wondering if anyone knew where to find (or hopefully expect to find) collections of the back-up Legion stories from the new Adventure Comics series (the one that started in 2009 with # 504, written by various including Geoff Johns, before Paul Levitz's return).  I tried a general Internet search without success.  My understanding is that the Superboy HC only collects the main Connor Kent Superboy stories from Adventure # 504+.  I have the individual Adventure Comics issues, but would much prefer a collected edition.  Any help would be much appreciated.

I am also curious as to how good Levitz's return to the Legion has turned out to be.  I haven't yet picked up Levitz's recent work but I was planning on doing so eventually.
