Best case scenario:
PhaseOne finally introduces a new Medium Format SLR AF body to finally put to rest the Mamiya 645 based body, fully functional and ready to ship. (which is not horrible but the IQ backs deserve something better, so do the lenses )
Leica introduces a new version of the Leica S with the 50 mp Sony sensor and improved features (high quality live view!), speed etc, again, fully functional and ready to ship. Also they will have on hand the 100mm f2 lens for the Leica S.
Hasselblad incorporates Live View via firmware into their 50c backs / cameras. Lowers prices across the board.
Canon introduces a new full frame DSLR (5D sized body but 1D class build and feel) with a new sensor with Nikon D810 rivalling dynamic range, resolution and great high iso performance and speed.
PhaseOne shows a prototype of a new MF SLR or a ready to ship worked over DF++.
Leica just has the 100mm f2 lens on hand and maybe a new Leica S (50mp cmos) but without live view.
Hasselblad has just what they have now.
Canon introduces a worked over APS-C camera (7D (II) maybe?) with a slightly improved sensor (no where near the DR of the sony/nikon sensor) with great video and a few printers.
Since I have some form of product in every brand mentioned except Hasselblad I'd personally like to see.
Leica introduce the cmos sensor camera with a form of cropped video (well implemeted) and cough, choke, under the $25,000 mark, somewhere at $15k or less. (probably won't happen) . . . and or an autofocus M series with excellent video. I think for Leica to increase the S series sales they're going to have to get to a lower price point.
Sony a full frame professional body with excellent in camera 4k video that auto crops to aps c and will allow track focus in stills and video . . .
though the one brand that will get my cash tomorrow would be a 7d with 70d type of sensor (autofocus video) and full functionality like hdmi out without knocking out the on camera screen. mini xlr inputs for sound and better highlight recovery.
Adobe with video lightroom with autotrackin and layers, batch processing and full xml support.
Blackmagic slightly slightly larger than the pocket with a super 35mm sensor, ef lens mount and excellent track focus and a still fuction because the black magic produces the sharpest of all video cameras.
All cameras listed with olympus grade image stabilization in camera and great preamp for sound.
Oh yes . . . and every camera a better, standard lithium battery.
Oh yes 2. Apple either sell or develop 64 bit, 4k capable fcp8.
