You can already get blasted by a space flower actually, they've been killing people for a few months now (and they're hard as hell). They even began to cripple space stations. The new ships arriving in 3.0 (which launches Feb. 27, we learned today), are smaller, cuter, and also a throwback to the original 1984 octagonal design:
The arrival of the scouts coincides with the Thargoids arrival at "the bubble", which is the area of space roughly centered around Sol that most of humanity inhabits. They began their invasion in the Pleiades nebula, where humanity has a few outposts and where AEGIS, an organization dedicated to researching alien life, has a lot of laboratories. Each week, a few more stations are attacked, and last week they finally arrived at the edge of inhabited space. I suspect when 3.0 releases, we'll be seeing a lot of these guys around inhabited space.
