Seiko SSK GMT. More colourways and varieties?

Given the popularity of the Seiko 5 GMT range, how likely do you think it will be that we will see more colours and varieties of this model? What's your thoughts?

The latest trend for Seiko seems to be releasing alternative colourways of their existing models so i would say that we very likely could see some new colours in the coming year 馃槈

I like the blue model and the black model but I hope Seiko release a Pepsi color馃檹
