WISKI, before reaching for your wallet, I recommend you study the issue further.
I am not aware of the XL2 being able to produce HD video. I think you are confusing the XL2 with the XL H1.
If you shoot wedding video, etc. then you are a business person. As a business person, it is up to you to read your market and decide what the marketplace wants. Does your market want HD wedding videos? Then it is time to get into HD equipment. If not...
I would think that upscale areas like Frisco, NY, L.A., etc. would feel the need to make the HD move long before backwater areas like Oklahoma does.
I've lived in SA. It is a large, metro area but not upscale by any means. I think you are safe without HD througout this decade.
