Thanks for brining the discussion back on topic.
Some excellent points have been made by all.
My feeling is that the logo has been designed in-house. If not, it could have been because it really is a tweek rather than a re-design. Any good designer could have/should have been able to make the revisions with little difficulty.
However, the actual form is a different matter...
Logo design can be VERY tricky, as anyone who has been involved in a re-brand or evolution of a brand will testify. I have spent the last 5-years doing just this and it is a thankless job.
