Hey, I just get an update and being told that the Starcraft II release date will be end of year 2009 if there's no problem comes in way during this period.

You can see the release date at StarCraft II - Wikipedia.

And that information is taken from these 2 sites.
"StarCraft 2 Planned for Release This Year". Shacknews.
"Starcraft II by end of 2009, Call of Duty expanding to new genres". Gamespot.

However, this is the expectation and there's no guarantee if it will be earlier or later.
Please take this information at your own risk.
