That 1200Mbps LTE Cat18 is probably not from 4CA with DL-128QAM. More likely a max performance is achieved while doing 4CA with 2 of the carriers being 4x4MIMO(vs 2x2MIMO on other 2) using DL-256QAM. Or with 3CA and all carriers on 4x4MIMO with DL-256QAM. So data 12 streams total with either option. Upcoming Qualcomm X20 modem will be also 12 streams capable.
Considering 128QAM is not defined in 3GPP Rel.13, I'd say the chart is most definitely wrong. You are probably right about the 12-stream 256QAM, but it could also be some sort of 5x20MHz combination or 2x10+4x20.
You won't see A75/A55 until next year. And there won't be any material difference since, by ARM's own admission, there won't be any efficiency gain going from A73 to A75. So long as SoCs are still thermal/power limited, there's no point in upgrading if it negatively affects time-to-market.

No A75/A55 - not interested.Santoval - Friday, September 1, 2017 - link
Still too early, it was just announced. Expect the first shipments in Q4, most likely December '17. Q1 2018 for reasonably high volume.levizx - Friday, September 1, 2017 - link

I am more interesting in performance gains from A55. After all, these are all thermally limited environments. Speculative OO just wastes power.Tigran - Friday, September 1, 2017 - link
