The next version of OpenOffice for Windows seems to be out of the release candidate stage and is available on selected download sites.
I have been using version 3.0 RC1 since it appeared and it seems fine, but I will download this final version soon. (size 127MB same as version 2.4.1)
Anyone wanting to download from the official site:
will have to wait a bit longer, as only RC4 is available there at the moment.
