Capability Of Wp

Hello my friends

I have a general question about capabilty of wordpress.
Is wordpress suitable for creating huge news site with this options :

1-each day added more than 2000 post on this site,
2-export rss news to every rss reader,
3-import rss news from other news site,
4-have advanced search system ,

and everything that you need for good news site.

Please answer my question exactly and if you have any opensource and free recommended system say it to me ( exp : joomla,mambo and etc )

Very Thanks.
