So it seems, in a slight deviation from the plans, this picture from Alton Tower's Twitter shows that the first main drop will now be inverted, or at the very least overbanked:
Notice the support on the far left is definitely supporting track from above, rather than below. Speculation is suggesting that this ride may break the inversion record in traditional style, after all.
I was at Alton Towers today, and tried to take some photos with my phone, but with the distance they're keeping around the construction site, you'd need a good camera with a big lens on to see anything of the construction in a photo.
EDIT: In fairness, it seems that the "speculation" about the ride breaking the inverson record, is not speculation; it is now actually almost certain.
In the picture below, it is quite apparent that after you drop to the left out of the station, you continue turning to the left and then go through a rising barrel roll (look straight down from the "m" in the word "maintain" and notice the track inverting):
Add that inversion to the newly apparent inversion on the first drop, and that already gives us a total of 10. If the other main drop is the same as the first, that would be 11. And with the surprises that this ride is throwing up, there could well still be another.
