the image is confusing as hell, you've got 3 things labeled 'AC1000' and 2 things 'AC1200'

Wireless is now getting faster than wired gigabit ports. Any chance there's a consumer 10Gb chipset on the way?

It's not, that's total bandwidth. Keep in mind that wi-fi speeds are not a measurement of maximum capacity in on direction like Ethernet is, the total of both upstream and downstream. So if you have 1300Mbit wi-fi, the max theoretical speed in one direction is half of that, 650Mbit. Much like how my 5Ghz wi-fi at 243Mbit-300Mbit is really running at 121Mbit-150Mbit in any one direction.

Well, more precisely, 1300 is the aggregate bandwidth of multiple spatial streams (and bands). With 802.11n the maximum speed you can get with a single antenna is 150 Mbit/s but that is with channel bonding (40 MHz channels), which is inadvisable on the crowded 2.4 GHz band. So the more antennae you have the more spatial streams you're using. It's kinda like if I teamed three 10/100 ports and called it "Fast Ethernet 300." It's misleading marketing.

Judging from the manual pg 47, they are using 80 MHz channels, which means 433.3 Mb/s per antenna based on the Wiki link from earlier, and that gives the 1300 Mb/s number with three antennae (just like a typical N router). Note that 80MHz channels are only possible on the 5 GHz band as the 2.4 is too narrow. Max throughput for 801.11ac is up to 86.7 Mb/s for a single 20 MHz channel as compared to 72.2 with 802.11n and 54 with 802.11g. They are now using 256-QAM with ac where they were only using 64 QAM with n. That is where all the speed improvement is coming from.

Wrong, which is the point I was trying to make I the first place. Ethernet doesn't work like that because if you go three 100mbit ports, that's 300Mbit/300Mbit you're getting as opposed to 150Mbit/150Mbit if it were half-duplex (more or less.) So regardless of what they did to the wireless itself, it's still limited and as you said, the wider the frequency the more likely you're going to pick up some interference from another band.

Judging from the manual pg 47, they are using 80 MHz channels, which means 433.3 Mb/s per antenna based on the Wiki link from earlier, and that gives the 1300 Mb/s number with three antennae (just like a typical N router). Note that 80MHz channels are only possible on the 5 GHz band as the 2.4 is too narrow. Max throughput for 801.11ac is up to 86.7 Mb/s for a single 20 MHz channel as compared to 72.2 with 802.11n and 54 with 802.11g. They are now using 256-QAM with ac where they were only using 64 QAM with n. That is where all the speed improvement is coming from.
Which is only good if you don't have anyone nearby with a 5Ghz network. We'll see what happens but I suspect that QAM-256's signal will degrade more quickly than QAM-64 did. As you start using higher order QAM modes, you get less and less noise resiliency from the signal itself.
