What in your mind is the cut off point for what systems count as "retro"?

Do you consider Wii/PS3/360 to be retro? Or does the Gamecube/PS2/Xbox/Dreamcast generation mark the newest gen that's retro? Or an even older gen?

What do you think?

Gen 6 and older is what I consider retro. Gen 7 IMO is to recent being at most 20 years old with the Xbox 360. 

Yeah Gen 7 still feels "modern" to me too, it has HD support, online out of the box, built in storage as standard, most of the core features of modern consoles.

That said, I don't quite feel Gen 6 to be "retro", maybe cos as an SNES kid I still remember how next level Gamecube/Xbox/PS2/Dreamcast felt at the time and how different they felt to say the early 3D of Gen 5 or the 2D era.

PS1/N64/Saturn and before it was I consider "Retro".

My gut feeling is anything 6th gen and before, in part due to age and in part due to game design philosophy. It’s very difficult to call 7th gen retro, for me, because so much of the DNA of modern consoles and games comes from that era — for better or worse.

Well, usually the two generations old systems are retro. Wii PS3 and 360 are definitely retro and now that the first 10th gen system is out, the Wii U, PS4 and XB One start being retro. Then again, games have been "modern games" for at least the last 25 years.

Gen 6 is a problem because PS2 lived so much longer than Dreamcast and you have Gamecube and Xbox in between.
On one hand it's not hard to claim that Dreamcast is still a retro console, but considering where games got to on PS2, that's not really retro anymore.
I kind of feel GTA3/VC/SA were turning point from retro to modern gaming era.

As a Nintendo gamer, I would say seventh gen is retro. Maybe my answer would be different if I played PS3/XB360 since those systems are HD (and are of comparable specs to NS1), but it’s hard to look at the SD bloom visuals of MKWii, Super Paper Mario, and Mario Galaxy and not see a retro system.

Wired controllers as standard, no HDMI cable support, convoluted and barebones online. All that really feel Retro to me, so I say 6th gen.

Technically 6th gen consoles had online and wireless controller options, and the OG Xbox could output at HD.

The online aspect was pretty archaic and the list of games that had that support was insignificant.

Yeah, I am aware. I had one myself for my PS2, but all of them were 3rd party, the standard for 6th gen was wired controllers.

Well, now you got me. I didnt know that. It was available right in the beggining or they added on later models?
