To loosely quote what has been made public
"It was a stabilised approach which experienced a windshear warning at 1100"
-So fair to assume they were on speed or thereabouts, which would be in the vicinity of 150-160kts
"There was a degree of uncertainty as to whether the autopilot was controlling the manoeuvre"
-No comment
"Pitch attitude peaked briefly at about 10 degrees above target"
-So in the go around, the a/c pitched to 28 or so degrees nose up
