Canon's response to Magic Lantern is pretty much status quo right now. Magic Lantern hacks haven't really unlocked any game breaking features on most of Canon's DSLR's, just features that lots of people felt were sensible things to have in the first place, i.e. focus assists, zebras, audio meters, agc disable, etc. Canon is notorious for protecting their products, and as long as the hacks don't result in decreased sales, everyone agrees to let each other be.
On the other hand...
I really like where the GHx community has done with the GH1, and GH2. This is one situation where a hack (or "firmware reinterpretation" as some would like to say
) has benefitted the consumer. Panasonic's response has been so good that many, including myself, feel that the GH3 doesn't really need a hack. Vitaly/Driftwood have done so much for that community that Panasonic simply had to respond. But I think the same doesn't apply to the BMCC. So much has been given at this price range that its mind boggling. I remember several months back that I nearly had to pay $500 to get DnXHD gradable on Resolve, thank goodness I waited. Sometimes I forget whats coming in this package, i.e. BMCC comes with resolve/scopes with free dnxhd support, all for free!
I feel that BMD, Digital Bolex and Kinefinity have opened the floodgates for affordable raw, so much so that the industry landscape will be very different in a years time, heck even by this NAB. More support for products in this range will arise, and competition will mold more feature packed products.
Well, I hope at least, sorry for my babble
