Ok so imagine this, bare in mind this is only just my thoughts and im not conspiring against MS here.
But say around 11:59pm sep 23rd MS release a nice now compulsary update for everyones 360s. What ppl dont know is that the update will kill ur 360, red rings globally.
Now imagine how many halo fans are waiting to get their mits on halo 3 24hrs later.
How many of those fans will realise that there is no way in hell MS would be able to fix all those 360 in months let alone weeks.
So how many ppl with think fuck it im gonna go buy a new 360 just for halo.
If this ever happened do u know how much money MS could make. However if it ever did happen there would be alot of questions and man would they be fucked in the long run.
Morale of the story is, watch out for any updates 24hrs before halo 3. You never know what might happen
also, if it does happen, you heard it here first.
