I'm sure each of the four finalists can get mass production. The question is mainly the $1m prize. And maybe an advertising advantage, not that it will probably be bigger than having Jerry Rice on your box and possibly in your commercials.
The "losers" will have to accept investors as partners, that's all. The $1m winner might not have to accept partners (well, unless ABC and Simon Cowell get an automatic free piece of the action...)
