Upcoming reissue Prime to have short stacks?

Speculation has been high about the upcoming Convoy from Takara. As we all know it´s only the latest in a series of reissues done by Takara over the last couple of years. And fans have been wondering what they could possibly do to make this figure different. Already we know that the figure will include the ´energy axe´ used in More Than Meets the Eye/Arrival From Cybertron, but what else could they do? Well, one popular theory is that the figure could feature Hasbro´s new shorter smokestacks. To add fuel to the fire, there was recently a Takara Convoy prototype/test shot/ect that was found with the shorter stacks. Will Convoy´s latest reissue include them? Looks like we´ll have to wait until February to find out...
