Actually, many schools are now offering 1 year MBAs.  Northwestern has a 1 year program.

Agreed, unless you need the degree to satisfy accounting education requirements to take the CPA exam.  Top (Ivy league quality) MBA programs don't offer nearly enough accounting classes to satisfy CPA requirements if you don't already have an undergraduate degree in accounting.
