@Hanafuda: Aside from Iwatas and Miyamotos public statements? No.
I'm not going to do research for you, you need to look the statements by yourself, or maybe someone is so kind to link some of the statements.
But the reason why Nintendo isn't hyping the games early, is because Nintendo already sell all the hardware they manufacture, so there's no need to promote hardware with upcoming games and most of the game sales are made outside the first weeks. Not announcing games early, leaves you a lot of aces to your sleeve, if the hardware sales starts to decline, they start announcing games earlier and it will boost sales again.
Just look at when SMG, MP3 and Brawl were announced, 1-2 years prior to release to boost the hardware before Wii was launced. Expect Zelda Wii being announced in the way oh yeah, it's coming out tomorrow (although, it was announced being in production in early 2007).
Ei Kiinasti.
Eikä Japanisti.
Vaan pannaan jalalla koreasti.
Nintendo games sell only on Nintendo system.
