How would it steal thunder? how would it be "stupid" ? Its technically the same thing. a device that handles all your media. It will be stupid to have a event this month and then have an event next month. It costs money to run all those lights. Costs money for the media to spend air tickets, the gas, rent a car etc to get down to the campus and to be honest its pointless to have an event for a single item like the Apple TV. The iPhone was a single event but see, the iPhone is a much larger product then the Apple TV.
money doesn't grow on trees. Even though Apple has billions of dollars, i'm sure they dont want to spend it on lighting for two events that could simply be merged since both products SHARE THE SAME MEANING. A multimedia device.
while I agree, I agree on different points.
Getting a set of appleTV, iPod, and iPad(I hope) announcements out, will fill out a suite for the holiday buying season. Remember that Apple stated emphatically the would not allow anyone to under cut them on price.
Getting the AppleTV announced puts them in front of the GoogleTV product suite (before the Xmas selling season). Think about a USB port for connecting to a webcam... FaceTime Den? (on your HDTV)
Getting an iPad 2 out there (facetime ready, and a 7" ), cutting the current prices and putting this out out as a replacement at the high end, put the pressure on the WinBooks threatening on the horizon
Getting the iPod Touch with a new Facetime ready, is the perfect "i don't want an iPhone because ATT sucks, but I do want facetime and apps!" (my fiance'... a Tmobile zealot).
Putting AppleTV ( maybe with camere... FaceTime den... eventually, FaceTime _Small business?), iPod Touch (pocket), iPod Nano (active wear), iPad2 7" (really, I see this as the 'purse model'), and iPad2 9" (both with facetime readiness), an iLife update with Facetime built in (for all the macs out there), it will establish a FaceTime as the de facto communications mode for humans
Couple this with MacBook Air (our lightest full function Mac with Facetime and a keyboard... our competition to the BlackPad;-) and you've got a fully 'in your Facetime' product line
