Sorry if I ask this, but the Sanus XF228-B1 wall mount is rated for 42-63 inches LCD TVs. I just wonder if I can still use it with my Sony 40" XBR6 LCD. Also I am interested in these mount because I will eventually want to upgrade my TV to a 46 inch size TV, and thus I will be covered by then. Let me add that I don't plan to upgrade my TV for the next 2 years at least. I'd appreciate you input here, and thanks.
