Many gamers are excited to hear about new console releases. We wait on the edge of our seats to hear the "Next Big Thing" in console gaming. And for many, the name can make all the difference. How many would have bought the Xbox 360 if it had simply been named "Xbox 2"?
For Microsoft, this means brainstorming creative names to capture gamers' attention. The rumored "Xbox 720" lacks creativity, and the further rumor of "Xbox 8" (possibly due to the use of Windows 8?) sounds even worse. The name needs pizazz. It needs to stand out. So the idea of taking that 8 and rotating it 90°, turns that lowly 8 into ∞. Infinity.
For Microsoft, This could be a jump in the sales to keep them ahead of the Competition. Name means everything in a product. Hopefully Microsoft understand this and capitilizes.
