Well, after sitting down to actually look over some of the stuff that Microsoft showed, I'll offer my PB take on most of it...
Halo 3: ODST
-Not ZOE3
-Looks interesting, and I can ALWAYS go for more JEEP ACTION
-Ahem....as much as a new game for an expansion......kinda ballsy. We'll see about that one.
Halo: Reach
-Not ZOE3
-Not much to go on, but I could ALWAYS go for more JEEP ACTION
-2010, which means Fall or Winter 2010, as they'll probably have a nice big showcase and pretty movie planned for 2010 E3. Call me later with detail of the JEEP ACTION kind
Metal Geal Solid: Rising
-Not ZOE3
-Until I play through all the other Metal Gear games, I don't really give a crap.
-Until Kojima makes me ZOE3, like I said before, he can take a Boing! bottle and shove it up his Kojimass!
Project Natal
-Not ZOE3
-Probably a good move from the business standpoint. Clearly trying to jump on the "Motion/Casual" Fuckton-Of-Money train. Possibly won't work due to most 360 owner primarily caring about above mentioned games, Rock Band, not exercising, anything but Motion Sensational movement. -Possibly will work due to popular Scene-It type games & Milton Bradley Arcade Games broadening the horizons of the system. My money is on the "Most 360 gamers don't give a [tornado fang]" wagon but we'll see in time
Facebook/Twitter
-Not ZOE3
-Facebook is probably not very popular among the nerd community, so most won't give a [parasitic bomb] about this.
-Twitter, *Gundam Wing Announcer voice* HOWEVER, is a very good move. Regardless if you like Twitter or not, it will soon become the basis of future journalism, whether in Tweet form or not. Working in the Sports News industry has shown me how just sports journalists use Twitter to find breaking news, because writers/other journalists posts Tweets on their Twitter account. This will soon be true with Game Journalism as well. Smart move, Microsoft
Zune HD
-Not ZOE3
-Still probably not an iPod killer, but will probably gain massive amounts of popularity due to connectivity with 360, beautiful layout and look, plus the Apple haters out there.
-Zune Movies via Live looks interesting. Really nothing bad to say about it. Will probably be successful.
That's primarily everything Microsoft I looked into. Did I miss anything?
