Ahead of the expected 1st April release/pre-order date, images have been released for the Marvel Legends 6 inch Avengers wave 1 for 2019.
The wave is a mix of figures from the MCU and comics. The MCU is represented by Ebony Maw from Infinity War as well as Captain America and Ronin from Avengers Endgame.
It is interesting that the Endgame logo is not used on the packaging - most likely as these would have been designed & developed prior to the announcement of the name. There are also the usual discrepancies that Hasbro and their fans have to suffer by working with early designs and the suit Captain America is wearing is silver vs the white we see in the latest trailer.
The MCU is also represented by the BAF which is an armoured Thanos who is built by collecting 6 parts from the figures (Captain America does not include a BAF part).
The comic book representation is Living Laser, Citizen V, Nighthawk and Hercules.
