The Conduit will sell 2.5 million copies... on the first day ...because it looks better, and plays better than CoD4, even if does not include online play.
Even if it were on the GameCube, which was faster/better than the first XBox and is practically part of this generation anyhow, it would be superior to any X360 shooter in existance, especially if it was a cooperative venture between HVS and Factor 5!
...
Sadly, the Wii-hater critics in the media will despise it, and its glory will be diminished... slightly.
Metacritic: 53
Lifetime sales: 2.1M... certainly enough for a sequel, and a 2nd chance at "hardcore approval"... not that those folks matter.
