I was thinking of picking up an XF100 for documentary and event work. I like the small form factor, 50Mbs/422 and can work around the limitations of a single chip if I need to. But I noticed that NAB isn't too far off and was wondering if Canon might announce an upgrade to the XF line, which was introduced in 2010 without many changes since. I noticed that the resale on used XF100s has dropped quite a bit lately. Think it's worth waiting for the latest and greatest? Would love to get 3-chips into the XF100 or at least improved sensor tech. I'd imagine used prices will really plummet if any major changes were announced.
