This sounds like a good step for SpaceX, can't wait to see what they've come up with!Sweetest thing imo is that this rocket might launch extremely soon, maybe even in 2019 if "Elon time" doesn't apply.
The raptor engine is the hardest part of the design and it's nearing completion. Blue Origin is building the New Glenn...
...and its BE-4 engine is seemingly a bit behind Raptor in development. Plus they're still building the building to create the New Glenn.
Since Blue Origin is still confident in 2020 for their first New Glenn flight, a 2019 ITSy launch seems possible to me.
