I’d be surprised. To beat E309 the summit would have to deliver a few major announcements. Metroid Other M, Super Mario Galaxy 2, New Super Mario Bros and even Golden Sun were all pretty major announcements. The only pending major announcements I can think of are a new handheld and Zelda Wii (but Nintendo said they’re saving that for E310). Obviously it depends on what you consider a major announcement but I’m not getting excited just yet.
