That's odd. I thought the yellow one was definite?

From Seibertron.com:Following yesterday's exciting news of a blue Alternator Tracks being featured in Previews magazine, Seibertron board member Senor Hugo contacted Hasbro to get the lowdown. Here's what he said:
On several websites, there has been images of a Blue Tracks from the Alternators line. The picture is from the July issue of Previews. Will this blue Tracks be the mass produced one instead of the yellow Tracks? Or will this blue Tracks be a variant?
Hasbro's reply was:
Hi Hugo,
Thank you for contacting Hasbro, Inc.
The Alternator Tracks will be yellow.
We appreciate your interest.
