AmiYumi set to play their own instruments again?

Not since 2000's Spike tour have Ami and Yumi attempted to play their own instruments at a recorded or televised live show, something they did pretty regularly in their early days. Well, no real information was given out along with this, but the following teaser photo was just posted on Puffy's staff blog showing rehearsals for the upcoming year end COUNTDOWN JAPAN 0809 show slated for 12/29 and 12/30 (I guess those are the days they're actually performing):


That's Ami with her Gretsch White Falcon as her purple Brian Setzer Hot Rod sits in the background. Clearly, something is afoot! I don't see why she'd have these at rehearsal if she wasn't meaning to play them. (And I don't see why her staff would point it out.)

It's interesting that she's said before that these particular guitars are too big for her to actually play.

No similar photos of Yumi were posted, so not sure if it's just Ami or not. But I can't wait to see this either way.
