Recently everybody is witnessing kind of preview/release season at Microsoft(most of which were most awaited products) viz. XBox360, IE7, 2007 Office System RTM, VSTO 2005 SE, new release of Office Live, Zune and Windows Vista RTM etc. (Also there were some spikes in MSFT shares too:)
Though there were some launches from other players (esp. in gaming console market) too like PS3, Wii
But clearly there is more excitement within Microsoft and Public as many amazing products are lined up and reaching their final stage and which are worth waiting!
