Kontact for windows?

[Diego M. Vadell]

Hi,
   Can I get the Kontact Kolab client for windows from somewhere? I googled 
for it , but I can't find it. In the kolab.org webpage there is a section 
with Kontact (proko2) on windows ( 
http://www.kolab.org/screenshots.html#kontact-windows ) . Are those outdated? 
Should I wait for KDE4 on windows to use it?

Thanks in advance,
 -- Diego.
