NumXL 2.0 (Beta) will be further delayed to address a few issues raised during our preliminary tests and to add new advanced models (e.g. ARFIMA, IGARCH, etc). The delay will allow our engineers to continue working on those enhancement and to apply patches for all known problems. Fortunately, there are no relatively big new issues, so it should be a short delay.
Tentatively, we are looking at the third week of March 2010 for a release date.
