I agree completely but we as modelers don't understand the business side of the issue.
Not only the 1/25th Centurion but their Chieftain, both the SU-100 and T34 too in the same scale. They had an Ausf A. Panther & a Jagdpanther for years too and why didn't they offer their 1/35th Leopard 1 instead of that A4? Why not continue that and the Gepard in Full Function?
They also had a 1/21 series armor kits too including the M40 Big Shot.
