Found it on the Dyxum.com forum
IFA, Berlin, 4-9 sept 2009: the A850 replaces the A900 (you already know that part)
(BTW: don't miss Leica announcing the M9 on the last day of the IFA on 9/9/09)
CES, Las Vegas, January 7-10 2010:
Sony announces the A950. Basically it is a A900 with a 32 Mpix sensor. No video mode. High iso.
So this means that Sony keeps 2 FF DSLRs in offer, one at 1500$ street price (MSRP 2000$) and one at 2000$ (MSRP 2500$).
Expect a 600mm lens to be announced between january and april.
(Side note: this leaves Nikon and Canon to announce a D4 and a 1D mark 4 respectively around march).
From this point onwards, Sony communication will be focalized on the soccer World Cup 2010 (in june). Sony was accepted to be one of the only 6 FIFA partners already in 2007, time to get the investment back...
NAB, Las Vegas, april 10-15.
Sony announces the A1000. This will be a revolutionary camera, basically a DSLR video camera hybrid. Sony wants to use NAB, because this camera is mainly a video camera. Sony feels that RED is eating too much market share from their Cinealta line, so they need a cheaper offer along their more traditional camcorders. Expect the A1000 to look a bit like the RED, costs roughly the same and be able to take 32 MPix pictures while filming in HDV at the same time. Expect a 28-300 lens with SSM (typical video range and SSM is silent, which is important for video).
Around the same time, the A2x and A3x line is replaced by smaller, cheaper crop cameras with video. Expect a very cheap A150 without built-in AF motor.
Marketingwise, Sony communication will be axed on the FIFA:
-a pro SLR with the A950 (*)
-a new type of camera with the A1000, perfectly positioned to celebrate the convergence between photo and video on the fields
-Sony video pro stands will assist the Sony soccer photographs and videographs
-all this so that the typical soccer fan wants to buy a camera of the same brand than the pros: the new A2x-A3x line.
(* a photograph which uses a photo camera incapable of video pays less FIFA royalties to be on the spot, that counts on a budget)
(Summer: A850 ceases production silently. Camera stays in program until stocks are cleared, just like the A900.)
Fotokina, Köln, september 8-10:
Sony announces the A5x, to replace the present "5" line. At the same time, a new FF DSLR is announced, the A820. Basically, a A850 with a 32 Mpix sensor and a smaller, plastic body. SD card replaces the CF slot. Video mode, built-in flash, simplified viewfinder. 1500$ MSRP, street price around 1000$ for christmas.
The A950 replacement is to be announced at CES 2011.
Just don't ask how I found all this...
