After thinking about it for a while I do still believe a transition period is needed before moving completely away from logos and colors. Maybe after 6 months or something, depending on where we are, we can revise it.
About West Harrison's point, I don't think we have the budget to do "very diligent, deliberate and massive publicity so that everybody knows there is a change taking place." So we will need a transition period. Also there won't be "constant brand changes". It is just 1 re branding process and it will take a while. But yeah, lets have some fun to warm up to the idea.
The coin have only one year. I don't think we need as long period as 6 months.
We had free publicity for a few days, so many already know what is happening.
Though, I wouldn't change any colors for some period of time
