Only evidence they'll get is if they actually DO it... the rest is conjecture.

But that is the way business usually is... SOMEBODY has to take a risk, and explore new markets. Sometimes it works, sometimes it doesn't. When it works, you make a boatload of money. When it doesn't, you are only out the development costs. Put it this way. If everybody waited for PROOF that anything they made was going to sell well first, before they made it, absolutely NOTHING would get made at all....
