When should the next Macbook Pro be expected to be released?

I have saved up enough money to buy a top of the line macbook pro. And I want one so don't try and convert me to pc. Anyways, I know apple releases a new mac or ipod the week after I buy one so this time I want a heads up. I don't want a 2009 model. When can I expect the 2010 mbp to be released? Thanks for your help.
