• Next patch update there will be a new talent cap of 110 points. Killing each Act boss will reward a talent point in every difficulty.
• There will be four acts and each act will have a final boss.
• Zones will be unlocked in a linear fashion, unlike the current design. I think this was a major point of confusion for many new players. Where do I go? The zones on the map will also be displayed in this linear order under "Act" tabs. So Act I will list the zones you have unlocked.
• Due to the new linear quest format, this may cause your available zones look sort of strange on the world map. You might have to go back and complete some earlier content to re-unlock zones you had before.
• You will be able to click anywhere on the background to do "Search Battle" outside of combat only when you're not in a city. I think this is a key usability feature for many new players.
• You'll encounter the first boss, King Grimden (Emperor Crush), at the end of Act 1. He is level 20 and I am not sure how hard this will be for first-time players. If someone could try this from scratch that would be pretty interesting to see the results. He's not insanely hard. He has about 7500 hit points.
• Every zone's mobs have had their levels adjusted for the new linear format.

That's all I can think of right now.
