The future of SD: Canon XL2 vs. Sony HDR FX1

Archived from groups: alt.video.digital-tv (More info?)

I am buying a new digital camcorder, but am trying to decide whether
to buy the xL2 or go HD. My question is, do I really need HD? I
shoot primarily weddings, documentaries, and short films to play at
festivals. For the docs and films I would really like the film look
that the new XL2 offers. However, I'm leary to sink a lot of money
into a format that may be extinct in a few years. Will I regret
buying the XL2 or will SD be around for awile? I'm not sure about
television broadcasting, but I may show some docs on tv. In a few
years will SD be obsolete and unshowable to audiences via tv
broadcast? What do other people recommend? Thanks.
