Nintendo (NTDOY) is back. After several false starts, Nintendo’s game release in mobile space has better momentum. Pokémon Go will likely grow its user base quickly. By finally embracing the mobile space, Nintendo will win back market share that it lost to Sony (SNE) and Microsoft (MSFT).Risk: Nintendo has buggy servers.Market reality: Nintendo is up 25% on anticipation of the company's success in apps.Other worthy points:1) Nintendo does not own Pokemon Go. The game was developed by Niantic for iOS and Android devices2) The company that owns this game is not publicly traded3) Did you try Pokemon Go? It sucks BUT may still end up being the biggest blockbuster game worldwide.
