When will my Phalaenopsis stem grow back?

[angel415]

I must admit, I was neglectful this winter - which resulted in an orchid catastrophe. The whole stem dried up, along with parts of the leaves (the leaves due to sun damage), resulting in this:

You can kinda see whats left of the stem inside the red circle (its a tiny bit hard to see):

A closer look at the stem (a bit hazy):

Its made some progress...I repotted it, leaving some roots sticking out. I did cut the dry spots off but not the little black spot on the top left leaf. (Should I?) I mist it daily and give it some filtered light and let it sit on the balcony in the shade. Will my orchid start growing a new stem anytime soon? I posted this exact same question on yahoo answers but didn't really get an answer I was looking for. (They said the stem should start growing by the end of summer/early autumn).

Tips and opinions are greatly appreciated....
