LR support for Sigma SD15 X3f raw files?

I have just purchased a Sigma SD15 camera - and also purchased LR 3(4) to do the RAW work since LR support .X3F files.

Then i found out (from the DPreview Sigma forum) that LR only support X3F files from the older SD14 camera.

SO ... does anyone know if and when LR is going to support X3F raw format files from SD15 and SD1(m) cameras?
