Appreciate what they're trying to do here but by the looks of things it just looks like the first in the line of many routers with the same functionality like automatic updates and increased protocol support. Supposedly ASUS are making their own OnHub as it's created by TP-Link.
The one ethernet port actually caters for me perfectly as I also run a switch, so really am interested by the increased WiFi performance without paying for anything else.
Not likely to pre-order as I'm happy with the performance of my ASUS N66U at the moment, but happily follow its developments.
