Now im getting it soon, and I kinda wanna know everything. I already knew something I never knew before and could lead me worried, the thing I learned is that the wifi connection takes like a hour for the update to show up :P .

And if u can answer this too: How many levels are the campaign, and is there weekend gambler? THANKS!
