Divisive

DIVISIVE....Yes, yes, I know this is trivial, but I'm curious about something. In his speech today, Barack Obama did something that I've suddenly heard dozens of times lately: he pronounced the word divisive with a short middle I. Now, I just looked this up in several dictionaries, and it is, in fact, listed that way as an alternate pronunciation in many of them. But until recently, I've never heard anyone actually say it this way. It's always been div-eye-siv. Did a memo go out or something that I missed?
