Super Mario Run was announced earlier this week exclusively for iOS for the time being. Kantan Games analyst Serkan Toto is confident that once the title hits Android as well as iOS the smartphone title could reach 1.5 billion downloads. However there is some confusion regarding the pricing for the game. A portion of the game will be free but it would appear as though to unlock the full game you will need to cough up some cash. Here’s what Serkan Toto says.

“As Nintendo’s first actual game for smart devices, I expect Super Mario Run to do extremely well in terms of downloads,” Toto wrote in a Kantan Games blog. “[I predict more than] 1.5 billion downloads over the lifecycle of the game, worldwide, on both iOS and Android and for tablets and phones.”

“The pricing has caused a lot of confusion,” said Toto. “Nintendo Japan is historically terrible in communications, and Mario creator Shigeru Miyamoto did a bad job explaining this part of the game when he demonstrated it for the first time.”
