Upgrade will be announced by late October and will ship by January. I'm also waiting.
I know many will disagree but look up the product cycles and dates of the announcement and shipments of both the 1D and 1Ds.
No disrespect meant, but I think you'll be utterly disappointed, man!
I haven't figured out if this is a real thread or not. I mean, this is a rumor site, and one can say anything even without evidence, but some statements just don't even make sense. Even a cursory review of the 1 series product life cycles reveals no such extraordinary possibility, and to assert that the 1DX will be refreshed in October 2013 ignores Canon's announcement that the 1DX was the amalgamation of 1D and 1Ds bodies. Unless you count the lifespan of the 1D mark II N, you just can't construe history to expect a 1DX refresh when the body is only a year and a half old.
we will probably see a new body in 2014 (or at least more announcements), but it won't be a 1DX refresh. Its more likely to be a new body with Canon's new 180nm mfg process and first competitive attempt at an improved DR, high MP landscapes type body. Its too soon to tell, but it appears this could be a single 1-series body, a single body that is not a 1 series, or we might see more than one body introduced or announced.
On a similar note, we can't expect a refresh of the 5D3 either, in 2014 (my opinion) since it is barely a year and a half old right now and still selling like gangbusters. When it does arrive, the refresh of this body would still, it seems to me, preserve the 5D heritage, i.e. high ISO wedding/event work, and not venture into the landscape space.
Personally I expect one camera in 2014 that will be sufficiently differentiated from the 1DX and 5D3 so as to preserve these for refresh in a couple of years time -- Canon's way of forcing the market. If they do introduce a high MP body that is not a 1 series, then it will have to avoid stepping on the 5D3's toes.
