Thanks for the input, I saw that they are pushing for end of January. I simply have no experience with this company.
I've been using DxO since v3.5. My only experience with them that relates to your question is that I asked them early last year when they'd release a module for the Canon EF 14mm 2.8L II USM on the 5D (the lens came out in autumn of '07) . They promptly emailed me back that "it's on their list."
A year later, nothing.
Currently I'm waiting for them to support the 5D II. Like the G10, they're saying January.
EDIT: Rereading my post, in fairness to DxO I should mention that I've had a couple occasions to deal with their tech support in the last two years, and both times the support staff was thoroughly professional and very quick to respond. Also, IMO their current v5 DxO Optics RAW converter has been excellent when used with my 5D and 24-105 zoom.
In sum I've had no issues their the performance of DxO's product or of their support -- only frustration that they don't have correction modules available for more of the lenses in my kit.
