It's a fairly rare thing in this day of instant information to have a genuine mystery surrounding a Transformers toy. Hasbro is hoping that at least one mystery can be maintained for just one more week. They've announced that they plan to unveil a world-premiere Transformers toy at the San Diego Comic-Con at 3:00 pm on July 14th.
Although that's not too far for me to go, I expect I'll just wait here and see the information soon enough when it gets posted to every message board on the Internet at 3:01 pm.
....Well, maybe not quite that fast, but it won't be long after. And I don't really have any other reason to ask for time off of work and travel to San Diego....
In any event, for the next week at least, let the speculation begin!
