A lot of people have left comments about the these two units, Sly Marbo and the Vendetta, and here we have some rumors as to what they may look like in the future Astra Militarum Codex that will be released on April 12th.
please remember that these are rumors. Lets face it though, this does make sense for the Vendetta.

1 ~ Sly Marbo will NOT be in the new AM codex. He's gone. (possibly a future dataslate)
2 ~ The Vendetta has gone up to 170 points, and lost half it's transport capacity, in that it can only transport up to 6 infantry (25mm) models. They can, however, still be taken in squadrons.
