You can always play this game, it's so much fun!
If you buy now, there might be a slight/silent update in feb/march. Or there won't and you buy then, only to see it updated in June. Or you hold out until June, buy this time you can't wait any loner, buy either way to then see a complete redesign and new processor generation in October just in time for the holiday season. On you wait until then and become a guinea pig for the beta version of the next generation of MBAs. Or you wait that one out as well and buy in feb 2014, when all initial issues of new generation have been addressed. Finally, the PERFECT TIME to buy an MBA. Honest, buy in 17 months. Or now. Depends on your needs. See where his is going?
