Nintendo's current strategies are very simply and brilliantly following the age-old wisdom of this rhyme:
Something old (Mario, Zelda, Metroid, Virtual Console, arcade on-rails shooters, catering to traditional markets and reinvigorating nostalgic relapsed gamers from the 70s and 80s, and they used older cheaper technology to have cheaper development costs to create opportunities for more cheaper games and more experimental games with smaller budgets and teams)
Something new (new product design, new ad campaigns, even a new logo color, IR pointer, speaker on remote, motion sensing, Nintendogs, Brain Training, Wii Sports, Wii Fit, WiiWare, creating and expanding new markets)
Something borrowed (they borrowed remote and pointer design from TV and DVD remotes that people are familiar with, borrowed Wii Channels interface from TV and a PC-style icon interface people are familiar with, and it's the only system with 100% full backwards compatibility with its predecessor)
And something blue (Brilliant application of blue ocean strategy, Endless Ocean, and exclusive Sonic games like Sonic and the Secret Rings, Mario and Sonic at the Olympic Games, and Super Smash Bros. Brawl)
Try and make that work for the 360 or the PS3. I dare you. Good luck.
Also, yes, this is what I do when I'm drunk.
