I finally made it to a comic book store today, and this is all I got:

X-Men: The 198 Files
It's not even really a comic book; its a handbook-type listing of 132 of the 198 mutants known to still have their power after House of M.  I don't read the x-comics (except X-Factor), but I still had to have this because I love handbooks.  I'm surprised Marvel would tie their hands by listing so many of the remaining mutants right away...
