How many planets at Alpha Centuri?

How will the Terrestrial Planet Finder mission locate new planets? Is it
some type of new space telescope?

Perhaps the question is not so much 'how many planets there might be'
but 'how soon we could look for them in a proper way'.

The Terrestrial Planet Finder mission is not due for launch before 2014
at the earliest, and I suspect there is not much room for prioritising
it in any way, because of the complex technology that will be involved.

But I remain optimistic we'll find those planets soon enough!
