WebKit2 port is working (I’ve tried it!) so it will be definitely ready on 3.8. User Interface is still under design but is the main goal for the next release so I guess that it will also definitely come -at least some parts of it.
What is more exciting (and with uncertain future) is the support for Chrome and Firefox apps. Igalia’s hacker Jose Dapena Paz has made (in the past) some work.

Epiphany 3.8 Roadmap
Although there is Chromium (and the dozens of the forks) and Firefox (which also has lots of forks), there is still a place (and a need) for the Gnome browser. Chromium quality has been reduced a lot in the last year in Linux (many crashes, huge RAM consumption) and I am thinking to switch back to Firefox which I left because it was slow, much slower than Chromium.
Web on the other hand is fast and lightweight, but it lacks of extensions and it has not syncing service, so it can’t be much useful at its present shape.
It is really hard to predict the future of Web. We just can hope we will see a better Web in 6months :)
