Problems NATAL Must Overcome to Find SUCCESS? (your list?)!

[ROBOTECHHEAVEN]

price is the only problem i can see it having, from being a huge blockbuster success. i think m$ will have the tech running almost perfect by the time is launches, and the games i am sure will be good to great at launch. and m$ knows this and with it entering its 5th of sales when natal launches , i think m$ will have natal ads everywhere imagineable too make sure it is off and running from the start.
