Countdown to the Legion's 50th Anniversary

You know, it didn't occur to me until I read it over at Duke Harrington's place.... That big teaser picture everyone is talking about - remember that Legion flight ring next to Blue Beetle's hand? Duke reminds us that the Legion's 50th anniversary is next year, with the April 2008 issue. That's just 13 issues from now.

According to this week's Lying in the Gutters, that teaser picture will tie into the 52 followup, called Countdown, where the week after 52 #52 comes out, is Countdown #51, counting down to zero. Might we see the return of some Legions with the multiverse during the series?
