The press release states: "The four figures fully convert between robot and cassette mode and fit into SOUNDWAVE when in cassette mode." I think that sentence just means that each of the four cassettes is capable of fitting into Soundwave's chest, but not necessarily all four at the same time. Since this is Hasbro issuing the 25th anniverary release and not Takara, it's probably going to be the dual-cassette deck Soundblaster repaint (like the TRU release). It'll be interesting to see what Hasbro does with the packaging. Unfortunately, it will probably be similar to the 25th Anniversary Optimus Prime packaging and not Vintage TF style.
