From tformers.com:

As you're probably aware by now, 2019 represents the 35th Anniversary of Transformers! And in honor of the occasion, Hasbro marches on with its G1 reissue series! The Facebook page for In Demand Toys has posted the first image of Reissue Soundwave with "Condor Cassette: Buzzsaw," surely a way of trademarking the extremely common word.

Soundwave is technically recreated from the original tooling, if previous reissues are any indicator... but you'll still notice a minor difference from your G1 Soundwave. When the character was recreated as New Soundwave Soundblaster during the 1987 Japan-exclusive Transformers: The Headmasters, the mold was modified to incorporate a slightly different door mechanism that could accommodate Soundblaster's 2-tape capacity. And thus has it been ever since. So it's a modification, but a vintage one, if that makes you feel any better!

In Demand says that preorders will begin "soon," but odds are also good that this will join the other recent G1 reissues and the upcoming reissue of Optimus Prime at Walmart stores in the US.
