Transformations 2011 has been cancelled, announces organiser Paul Cannon on the official website. Transformations 2011 was going to be a London based Transformers Convention taking place in April 2011, the first since Paul's previous Transformers convention Transforce stopped running a few years ago. According to the website, the event was cancelled simply due to a lack of registrations.
This means that the UK is back to being a single dedicated Transformers Convention with Auto Assembly. There are other events that take place during the year which include Transformers, but there is no other dedicated event.
For those of us who were fortunate enough to attend Transforces in the past, I can tell you that, with the exception of the last TransForce, each event saw the convention grow with an atmosphere similar to the last two Auto Assembly's.
