Questions for people who have the Xbox 360 & live 06

[VlaDiv]

1. How is online play? Is it similar to live 06 on current xbox - 80 % of shots from half court go in, 10 steals a minute, very arcadish etc. How long are the quarters?

2. Is it worth upgrading to 360 just to play live? Without a dynasty mode, slam dunk/3pt and no superstar moves I'm pretty hesistant. Does it even have basic freestyle like from live 05?

Thanks
