Asian session action - trend trend trend

Been looking back at the charts for a bit and noticed that during the Asian session we pretty much see a nice trend rather than the whipsaw that US likes to create.
Is this something that has just been happening this week or is it pretty normal for the overnight session to be like this.
From a very simplistic point of view, it seems if we determine the clear trend by say 5am GMT we can jump on for a nice gain and get out by 8am and reassess?

Am I just clutching at straws?

You must only be looking at some very recent charts; the asian session typically (pre Lehman Bros) was rangebound. Made for some good trades on the breakouts of the asian range. How things have changed
