Let's check; the fighting genre.
7th gen Fighting genre vs 6th gen fighting genre. (I'm splitting it up as that will make it easier for future conclusions, not to prove that the Nintendo consoles (for instance) are doomed in fighting).
Machines - 6th gen - 7th gen - difference
Nintendo consoles: 11.25M - 13.75
Sony consoles: 55.39M - 9M
Microsoft consoles: 5.9M - 10.9M
Handhelds: 0.14M - 15M
Total: 72.68M - 48.65M
For consoles only: 72.54M - 33.65M
Last gen, there were sold ~ 1.7B games on consoles. This gen we're at 750M so far. In other words: There have been sold 46% as many fighting games on consoles as last gen, and 44% as much total software. Compared to other genres, the fighting genre is selling dead on the same as last gen.
As for Fighting vs RPG, it's at
Machines - Fighting - RPG - difference
Wii - 13.75 - 5.06M
Ps3 - 9M - 5M
X360 - 10.9M - 19.89M
Total consoles: 33.5M vs 30M.
Handhelds:
DS - 4.5M - 66.38M
PsP - 10.5M - 18.05M
Total all machines: 48.5M vs 85M.
The RPG genre is definitely larger than the fighting genre all around. On consoles alone, they're equal.
