Why is 5 years too long? Do you want a sequel every 2 years until you get bored of it (aka Resistance, Killzone, Ratchet and Clank, Gears of War, Halo, Call of Duty etc

? 'Cause I sure don't. I'd rather wait 5 years for an excellent game, then a game that's just thrown out the window (I'm not saying any of the games I mentioned earlier are garbage).
Also, I heard somewhere on Gaf (not sure if its true) that Nintendo already develops the games in HD and then makes them SD. Is that true, or complete and utter bullshit?
