Let me do the math for you:
Did you know that there was a 16-bit console years before the Genesis, TG16, Neo Geo and Super Nintendo came out??? did you buy that system? can you tell me the name of that console?
Now, i'm going to do a revision of the last 3 eras (only the famous consoles)
5th gen:
Sony Playstation: 32-bit
Sega Saturn: 32-bit
Nintendo 64: 64-bit
6th gen:
Sega Dreamcast: 32-bit SH4
Sony Playstation 2: 64-bit Emotion Engine
Nintendo Gamecube: 32-bit Gekko
Microsoft Xbox: 32-bit Intel custom Coppermine-based (Pentium III)
7th gen:
Microsoft Xbox360: Xenon (Power PC-based)
Sony Playstation 3: Cell (Power PC-based)
Nintendo Wii: Broadway (Power PC-based)
Look that in the 7th gen people don't even care about the "bits"
BTW, all the x86 PCs have 32-bit CPUs since the Intel 80386 back in 1985... The 64-bit ones are recent, and people still buy 32-bit PCs with 32-bit Operating Systems, and they play heavy games in them.
The CPU specs are more than the "bits", and the console specs are more than the CPU... And guess what, most people don't even care because IT'S ALL ABOUT THE GAMING EXPERIENCE, if the user is happy with the games, the user is happy with the console.
That reminds me of 2 videos Play Value did about the failed consoles:
P.D.: It's 4:47 A.M., i just finished a project i was working with, i visited the site and didn't read the entire OP, so i didn't realize i attacked someone who's actually on my side... But i'm too tired to correct the post so i rather leave this post-data.
