early Marvel trade solicitations

Recalling my response to Brian Hibb's Tilting at Windmills column — where he decried how early some publishers released trade paperback solicitations and how that can hurt monthly sales — I did notice that Marvel has released their trade solicitation for the rest of the year, including a House of M trade paperback. Though I like the idea of hearing about trades this early, certainly it would be ridiculous for DC to solicit an Infinite Crisis trade paperback before the first issue has even come out yet. It guess it would be equally inappropriate to list an OMAC Project trade paperback, as well; then again, does anyone really doubt that there will be one eventually, just the same as with House of M? I recognize that the solicitation makes it a little more concrete, but ultimately, is there really that much difference?
