I think Jim Seaman is right on the point.
Technology that exist in lab right now, will become available to us in next 10 years, why, manufacturers should recover their money from investing in research and additionally their expected normal daily profit.
Duncan; If you replace the memory card by the wifi card that sends your images to pc/mac, can you tell me how the wifi card reads the image files that are now over you table or in your hand?

Canon has the wifi built in the power grip but I believe the price is around $800 to 1000 that means they are not building it for me unless I feel confidence on Bad Ebay in next ten years for one.
Two things I like to surely see in DSLRs and I mean soon, first Real Hard drive (I said real because I am aware and own several IBM microHD card that are between 128MB WOW, and 340MB, of course this is to exclude a few of non functional 1-5GB ones that came by third party manufacturers that turn to a toy or a memory symbol once they fall from finger tip to the palm of hand or just by themselves plan not to work anymore). Installing 2.5 format laptop HD of say 160GB is so simple, small and easy that I am not sure WHY it is not done yet. Someone once told me the moving internal HD motor can act like a gyro... what a joke. We have video camera right now with HD that work perfectly without driving you out of your ballance...
Then I like to see the LCD on DSLR to be movable like many other cheaper point and shoots like Canon S3. Why? It is very practical for low angle view, hight angle shooting from top of the head of audience standing in front of you etc Of course then you like to see full time display option like the PnS to go with this and heel todays batteries can take care of the needed extra demand.
Of course internal GPS would be a plus, High definition TV, DVD compatibility and projections display on the wall, are appreciated and surely phone, electronic ID to be used instead of passport or driving license, photo ID, credit card, and also a flat hard under surface of camera body to be used for ironing the cloths now that there is enough internal heat build up are all in the wish list...
