Nothing says "Welcome to Nintendo Land" like free admission.
Nintendo will be considering pre-installed software on Wii U in some markets. This came up as part of the Nintendo analysts meeting at E3 2012. Although they didn't reveal any specifics, they have mentioned multiple times during the event, most recently during the Developers Roundtable, that they consider Nintendo Land to be to Wii U what Wii Sports was to Wii, making it the obvious candidate.
Nintendo has been pre-installing software on their handhelds since the 2009 release of Nintendo DSi XL. The Nintendo 3DS came installed with Face Raiders and AR Games.
