Do you mind me asking what is the use case? What clients are you planning on using with it?

There's not a lot out there yet - a consumer grade router like the Asus RT-AX88U Has the 8 ports but not tripe band. The GT-AX11000 has triple band, but only 4 LAN ports. 

If it was me, I'd be looking more enterprise level, maybe if it's not urgent waiting for the likes of Ubiquiti to release an .ax AP and use it in conjuction with a 10G switch. 

It seems like Aruba are some of the first to have .ax APs to market - try around $1300 per AP, and I expect you need to buy some form of controller or sub for them?

Zero.

Such a product doesn't exist and probably never will (well until Mikrotik eventually build 802.11x into products). A router typically doesn't replace a switch - they're two very different things.

I too am interested in the use case and what 802.11x clients you're planning to use.

My pick would be Aerohive right now for an 802.11x AP.

TwoSeven: Didnt know the standard had been ratified yet

Found what I am after

TP-Link Archer AX11000 Next-Gen Tri-Band Gaming Router

And from my testing, it a faster switch then a few Cisco systems I have tried. (its has 1.8 GHz Quad-Core CPU and 3 coprocessors to manager traffic)

Seriously - don't waste your money on that. Buy a real access point. Consumer grade access points are both an absolute ripoff in the higher end and simply don't perform well.

Also, with WiFi 6 you'll need multiple access points as wall penetration really isn't there. One router just won't cut it. You're best to wait until one of the bigger players release a proper access point.

So you already have one then? Why ask the question in the first place?

That's a pre-draft device that isn't fully 802.11ax compatible (and says it doesn't even meet all draft 3 requirements, let alone draft 4) which would immediately put me off buying it. 

If you don't have .ax clients there are virtually no gains in having a .ax AP - and even then the real benefits that .ax offers such as colored bss are only going to deliver benefits in dense deployments so you'll see zero benefit on a device such as that.

But I do not want to spend money and find out all the reviews are wrong, so I am asking here, and looks like I need to do more research before spending any money.

I have to get a new 8 port switch for a new house that is getting built, (Cat 6a cable run throughout the house back to a central patch board) and before buying a 8 port switch and a router, I wanted to see what it out there that and having one device that is both a 8 port switch and a fast wifi router supporting wifi 6 made sense instead of getting a wifi 5 device.

The price of the 8 port switch, wifi 5 triple band router was $450 NZ, the price to get the wifi 6 triple band router, was $500 so it looked good on paper and I came here for advice.

The only device I have so far that uses wifi 6 is my S10, but I wanted to future proof, since there was only a $50 difference in price. Would you buy wifi 5 over wifi 6 if there was almost no difference in price even if you had no use for the wifi 6 for now?

I guess the main question is what ax clients you are planning to use it with and what benefits you see in deploying ax right now. With no ax clients you won't necessarily see any benefits, and even with an ax client the benefits may not be significant, particularly on a SOHO device on home network.

In large scale enterprise deployments ax can and will deliver some pretty impressive benefits particularly with bss colouring. 

I'd go with a separate switch and well established AC AP, depending on how big the house is you could look to mesh but based on experience you'll be better off with each mesh point being cabled rather than using a wireless backhaul.  A lot of folk will say don't buy TP-Link etc but honestly I've had zero issues with my $50 8-port TP-Link gigabit switch.  Depends if you want managed or unmanaged.  

Ok, for now, will just get a switch and use a cheap wifi 5 router until wifi 6 standard is fixed, then relook at spending money.

If you were willing to spend ~$800 on a router then look at the Ubiquiti AmpliFi and be done with it. Again, don't get sucked in with consumer grade stuff.
