Random House publications now available on iBooks

As rumored, it looks like Random House -- the last big publisher hold-out -- now has books available in Apple's iBooks library. Or as Chad put it when he woke us all up at the crack of dawn this morning:

Born to Run from Christopher McDougall and Tim Ferris's books can now be downloaded!!! Whoot!

Is this part of the iPad 2 event announcement later today? Seems a bit of a coincidence timing wise if not... Either way, anyone want to recommend some other good Random House books to check out?
