I imagine that canon will use the technology gained when making that 120 megapixel APS-H sensor to make some incredible cameras. You just wait... The future of digital photography isn't as noisy as you think.
Make everyone happy:
151MP, full frame with APS-H & APS-C crop modes; and 4:1 (37.8MP/8K+), 16:1 (9.4MP/4K), and 64:1 (2.4MP/2K) pixel binning.
