Marvel collected editions decidey people (like you're even reading), listen up. You're missing out on a golden opportunity here. You have a nice little back catalogue of Brian K Vaughan X-Men comics that you haven't collected into TPBs because sales sucked the first time round.
So. Now that he's big and famous and all. How about making one sensible-sized volume out of the lot of them? X-MEN VISIONARIES: BRIAN K VAUGHAN, featuring the as-yet uncollected X-MEN ICONS: CYCLOPS and X-MEN ICONS: CHAMBER miniseries, his story from X-MEN UNLIMITED #22, the X2 WOLVERINE PREQUEL (preferably with Vaughan's own dialogue reinstated on the Wolverine book - an issue he complains about on his web site) and hey, why not throw FCBD RUNAWAYS/X-MEN in there as well!
It'd make for a great package (especially if you use Jo Chen's RXM cover on the front) and despite the somewhat unsuccessful nature of those mini-series BKV obviously has big "name value" in the graphic novel business now (hence DC putting out that Batman/Wonder Woman book for no other reason). Marvel's sitting on a pot of gold there!
