It takes much longer for something to be obsolete than people may think. Difference between "Obsolete" means "Unusable". There is also "Improved" and "New for Newness Sake". The M9 improves on the M8. The KAF-18500 used in my newest digital camera improves on the KAF-1600 used in my oldest digital camera, 1992. The KAF-1600 series is still in production, and gets use in the scientific industry.

So it's been in production for almost 20 years.
Today I was telling my co-worker that the M9 could produce a 36MByte Raw file and that was the same file size as the Digital Images that I used a VAX 11/780 to process in 1982. The LANDSAT 4 images were 6000x6000, 8-bits per pixel, and 7 spectral bands.. So it had more resolution, and more colors. No Photoshop, I used FORTRAN to process it.

I first used Photoshop 3.0 in the early 90s. I still have it, and still run it. It works with the first Digital camera that I bought, which still works.
