HK online store Robotkingdom has just listed a pre-order for a reissue of the Gen1 Hotrod toy in June... noted as a Walmart exclusive (in America).

If this ends up being true, there are so many questions... like, is this the start of a new round of reissues from Hasbro, or, is this just a one-off toy because Walmart was the exclusive home of the Hotrod character from the TF5 movie, or, Hasbro had rushed to production various random exclusives for ToysRUs late last year to help keep them in business (before the decision to liquidate the business), and now Hasbro are having to find other retailers for those exclusives.

Hopefully Hasbro will make some announcements about this soon, as the next official event for announcements is SDCC in July, which is after this one comes out.
(if not, we will probably have the usual Chinese leaks, if this is the first of a series)
