GSC already released probably one of the best Saber figure thus far ! Saber Lily Distant Avalon.
Recently, GSC announced new variation to Saber Lily know as Saber Lily Golden Caliburn.Scheduled for February 2010 release, available as Wonder Festival 2010 Limited Edition Product
From the facial expression, one can observe the GC version has more subtle smile and gentle feminine eyes. Also note there is a black 'tie' to the neck which is not on the DA version.
Apart from the expression, main difference to the DA version is the removal of her armour, alternatives to her feet and shoes, and of course probably one of the main highlight Golden Caliburn scabbard!
So instead of metallic armour, you get more alternatives such as white gloves, white pantyhose,med/high heels, crystal-like skirting (white in DA version).
Further the base is rose coloured and c/w logo.
The GC version is a limited product exclusive to Wonder Festival 2010 in February. JP can order from GSC website in February but it'll only to delivered in mid June. Maybe, hopefully, they'll make it available for mass in near future.
Meanwhile one consider another new release on Saber known as Triumphant Excalibur release.
