Actually from what I learned 1.3 is only just a bug fixing patch. It is better for the final release to have all the cool new maps including the updated New york maps, graveyard and ShipBelow map. Also the other maps for the later part of the story. It will be a huge overhaul which is what I think Trasher is planning to hit us with 
Yes the hype for Revision might make you impatient, but will definately be worth the wait. Project 2027 is looking like it is going to be released soon as it is nearly done. check out the site http://planetdeusex.ru/2027/
Yes there are still good old games that are waiting to be discovered that can help you wait for Revision. When I couldn't wait for Revision I played it again and again and reported bugs to good ol Trasher and bjorn
