I'm not sure tbh, I think these have been released in batches but who knows what's remaining. Bear in mind the single game hospitality which will work out more for the club in the long run (if sold every game of course) will still be available. Who knows what they'll charge for the tunnel club per game for instance.
If I recall correctly, just some images. Here is one:

You can tell the 60k ones as it had a gap between the South and side stands.

After it switched to the smaller one fairly soon afterwards, there has been subtle changes like where the car park was going to be (inside the west stand for instance) and the western terrace which was only added after the civil engineers got involved post Meis leaving the project.
