I wasn't suggesting that a massive headline pixel count is a good thing, I agree it sometimes is not. But manufacturers will follow whatever fashions are followed, which may mean higher pixel counts in future.
I've just recently got a new camera myself, which sports a 20 megapixel sensor. It supports a 'Raw' mode as well as producing jpg images and, for now, I'm saving both. That means about 30-40MB of data for each photo...
I've already made quite a hole in the 64GB sd card that I initially stuck in the camera. Admittedly though, I'm still playing with it trying to learn its capabilities, which might mean a whole afternoon taking dozens upon dozens of pictures of the garage at different settings so I can compare the ffects.
