The Amiga scene as a whole has been pretty much dead, man. You can measure this from demoscene activity (which is your main source of coders dedicated to the platform in question). Spectrum and C64 have been thriving demoscene-wise so you get a lot more releases, this includes games (of free and also commercial ilk).
I for one would love to have more Amiga software released, specially software that uses stock hardware, however there seems to be not much interest in this platform. I would hazard a guess here and say the 68k architecture is a bitch to learn and puts off most neophytes. Also, doing the graphics and music for an Amiga production usually takes a lot more work than a, say, Spectrum game.
Fortunately it seems people are getting back at the Amiga demoscene, the last Breakpoint probably doubled the number of last year's Amiga entried, and the quality bar is rising. But it will be a slow curve, at this pace, to get where the Spectrum or C64 demoscene are.
