Apple has a great record of leaking models the day before with specs and prices. Given that no such leak has occurred to date, I'd say it's pretty unlikely that they'll arrive tomorrow UNLESS we see a big breaking story before days end.
I write this awaiting my quad core unit today. Don't get me wrong, I'll buy the new Penryn model the second it debuts.
