Glad I could clear that up for yah.
Nintendo revealed they would show off there system before E3 last year and they did...it wasnt suicide. Plus with how well Microsoft did last E3 you really think they will do any better. At best they will say at the end. Oh yah we have started thinking about our next system but wait till E3 2013 for info.......Then again with the 2012 end of the world this year we wont even ever see the 720/PS4. And with the PS4 sony is in financial unstability right now. Spitting out a POWERHOUSE system would be shooting themselfs in the foot and would risk bankruptcy. after the failure of the PS3 launch they wont make that mistake again.
Yeah and what happened after E3 2011? Nintendo sold the least amount of Wii's and wii software because people knew that a new console was coming out. The wii was starting to decline anyway.
Microsoft doesn't have that issue. They are selling 360's like hot cakes and won't announce the 720 right now, not until at least e3 or else they will see a sharp decline in 360 sales and halo 4 wont sell as well because people know next year there is a new console. An extra three months of revenue is a lot of money in this industry (it's a whole financial quarter) so announcing the 720 now or in June plays a huge difference financially. Basically, don't take Microsoft seriously when they say they won't announce new hardware at E3
