"2. On Xbox Live, it would break 1 Million easily, proably within a Month. The Halo crowd would eat it up straight away, just like they did with ODST and Halo Wars (The best selling RTS on consoles)."
2D shooters aren't as big as strategy games right now, so assuming sales would be that fast shows you aren't looking at the bigger picture. They wouldn't buy it because it would have Halo in the name. They would buy it because it ALSO looks like a game they want. If they don't want a 2D shooter, they will not buy it.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
