Analysts see Project Natal adding billions to Microsoft's revenue!

$1.7 billion in revenue in FY2011 + $2.3 billion in revenue in FY2012. They claim a retail price of $85. They also say in 2 years (so more or less end of FY2012), it will have a 56% attach rate? So they expect Natal to sell roughly 47 million units, meaning 56% attach rate puts it at roughly 84 million units. Do they really expect the 360 to sell 47 million units over the next 2 1/2 years, when it has sold less than 80% of that in more than 4 years?

I don't think the analysts are doing the math like that.  The additional revenue will not just come from selling Natal like you calculated.  It will also come from selling Natal games, and it also probably includes the revenue from the boost in console sales the 360 will see.
