Does the current version of either SIG or SIG Pro work with J! 1.5 natively, WITHOUT the legacy plugin?

If so, which... SIG or SIG Pro?
If not, is there an estimated release date?

On the homepage, there's a link titled " Check out the exclusive Joomla! 1.5 demo " which is why I ask.

Thanks in advance.

Hi!

I run SIG Pro in native mode of Joomla 1.5.1, Rhuk Milkyway template, without any problems whatsoever.
