On the test server amongst a lot of other new goodies, you can preview the new in game browser.
As you can see, it actually displays this blog exactly like it should :). I assume they took some rendering engine like webkit and used that to pull it off. The new blog on cosmos is interesting. Cosmos doesnâ€™t interest me all that much, but the new email client will be such a blessing. The current one is so horrible, itâ€™s not even funny any more ;).
UPDATE : Link to technical devblog on the new browser.
