Let's look at this another way perhaps.
Hornby has been going through some major supply issues, during that time they would have had several models that they wanted to produce but felt they couldn't proceed on because of the issues they had.
If during that period some of these plans were being leaked between the various Chinese factories as has been hinted with regards all the companies then it is possible that the other manufacturers were trying to steal a march on Hornby whilst they were sorting themselves out.
In which case what has been happening with the radial, King, 71 and now MN is that Hornby are claiming their models back and reasserting themselves in the market. Add in N gauge and that makes Hornby look to be in rude health and confident.
