As noted in other similar posts: Roku uses 3rd party chipsets in their hardware. It's up to them to add features that Roku can use.
WiFi 7 is VERY new, only finalized last month. Currently, I assume it is little more than flagship phones that support it. WiFi 7 routers are VERY expensive.
Remember that Roku's, even the Ultra, is mainly a mass market device. I assume 6E may come with whatever hardware upgrade comes out, but I wouldn't count on WiFi 7 on general consumer devices for a few years. To be honest, the processing speed of the Ultra is still competitive with many other upper-end consumer streaming devices. It's also cheaper than some of them, like the Cube or Apple TV. Unless you are streaming local ripped 4K material, you only need 16-25MBit for Internet streaming.
