TFS plugin for eclipse

Are there any TFS plugins available for the Eclipse IDE? We are trying to centralise our SCM, and since we also develop Java 2 EE applications, we would like to have TFS integration in eclipse.

Which plugins are available? Which have you found most useful.

I heard that Microsoft may be releasing one, does anyone know about this?

I have had a look and found the reviews of Teamprise looks good, however would like to have > 1 option!

Thanks in advance.

There might not be a free plugin and this SO question reports several alternative to a direct Eclipse integration.
Otherwise, there is Teamprise:

As Martin (mrhinsh) details in his answer (go upvote it):

Since Teamprise was aquired by Microsoft it has become Microsoft Visual Studio Team Explorer Everywhere 2010 (as mentioned by the teamprise.com page, and detailed in the Microsoft teamprise FAQ page).
It might be accessible for anyone with a MSDN licence.
(thijs confirms in the comment: "its free with an MSDN (Visual Studio Ultimate with MSDN) account")

The blog post "Even Better Access to Team Foundation Server" by Brian Harry MS announces:

Starting today, we are eliminating the requirement to purchase Team Explorer Everywhere separately.

Before today,

Team Explorer Everywhere users had to purchase both a Client Access License (CAL) and the Team Explorer Everywhere software,
whereas Visual Studio Team Explorer users only had to purchase a CAL – the Visual Studio Team Explorer software has always been a free download (TE 2008, TE 2010, TE 11 Beta) for users who had a license to access a TFS server.
Starting today the story is the same for Team Explorer Everywhere (TEE 2010 with SP1, TEE 11 Beta).
