Based on last season's average attendances, Sunderland (3rd), Sheffield Utd (8th), Norwich (9th) and Middlesbrough (10th), would all have made the combined top ten.
Bear in mind the figures I quoted are merely the biggest attendances so far for each of the clubs, not their overall average. It'll be interesting to see how it works out over the season, especially if some of the bigger clubs in the German second tier struggle. But there's no doubting there are some big clubs in that division this season.
