The Snakas Blog has posted images coming from Taiwan of these two brand new toys found in stores. While these are made for brand recognition/growth in BRICS countries, some toys have made it to the US as well, like last year's Prowl and Jetfire which were found at Wallgreens. It is unsure if these two will as well. Speaking of Prowl, it seems Windcharger Sideswipe shares the same engineering. Shockwave however is completely new and turns into a cybertronian spaceship very similar to RID's Cyclonus.
Previous toys in the subline have also been found at Universal Studios but at "exclusive-style" prices, so these might as well. For those unaware, these are voyager sized toys which sell at the deluxe class price point when found at retail. For a review on the previous Prowl release in this line, you can click here.
