The Caminol10n project should be able to add some new languages soon. That's good news because this means Camino will be available in language not supported by Apple/Safari.
On the Camino development side, code is being commited by Pinkerton while Josh is organizing documentation, website and other administrative duties needed for the 1.0 release. I have not made much progress on the spell checker front but maybe this will be integrated into seamonkey and thus we might get it.
