Pretty sure it's triple cam next year.
One for each color channel, but why not go for 30 cam - 10 for each channel? Either way, for quality work nothing beats a DSLR and its one sensor with physical attributes that quickly explain why it's better suited for most tasks....
But for spying on family and friends, that cell phone camera can't be beat because nobody gives a bleep about color accuracy, so why do Homer Depot and other stores tout those virtual wall painting apps, which are not just buggy because they're poorly made but because color accuracy isn't going to be legitimately good enough...
