Those are worthy things to add/improve. But you're not providing evidence for the earlier claim that removing video lowers price. (Apologies if you weren't saying that).
I didn't claim that removing video lowers the price, but it takes away a lot of resources on development. Most people seem to think that if they invest 2000$ into a cam those 2000$ are all in the body. That's not true... the component are worth something around 300-400$, maybe more, maybe less. The rest is profit, and much more important it's the cost of developing the whole device. Add some licenses for the codecs, too. So, if you fiddle around for 3 Months in a team of 4 engineers just to get your Log2 Codec working is something which takes the price of the cam to a higher level. Because the paycheck of those 4 engineers has to be payed.
At the same time (for stills) more important features are blocked or postpones on the schedule. People tend toward the swiss army knife where every feature is available. Afterwards they pay twice the price for having features on it they barely use. My videocams are totally different devices, if you seriously want to film something the whole way tro hold the body is wrong with DSLRs. So, the first thing pro's attach are useable grids
