Hi senseiteekay,
this is my prefered scenario, but this can be wrong, of course.
If we would see a correction back to the level of Blue 4 after the Blue 5 was reached, the probability would be high that the upward trend continous.
It's also possible that wave Blue 3 and Blue 4 are nested wave 1 and 2 (of minor degree), and "the mother of all wave 3's" is in front of us.
We don't know it, but time will tell.
BR,
