Yeah it's also like how Nintendo made Excitebike 3D for free when the eShop launched until like July to get people to go and check out the eShop. And on the holidays they had Zelda: Four Swords for free until February to give a little holiday incentive. "Check it out now and you can get this for free!"
A month and a half is tons of time, heck most games make all their sales in their first week.
