I think the name Visual Studio for Mac is another bad decision like all the rest. They say it's using a lot of code from Visual Studio, but to me that seems like an implementation detail and I don't care. In fact, if it feels like Visual Studio, then they've failed. It should feel like a Mac application.
My first choice would have been to stick with Xamarin Studio. On the other hand, this sounds like a significantly new product, and so if it deserves a new name I would have seized the opportunity to launch something new that's going to get developers attention. Visual Studio for Mac does the opposite. It makes me feel like I know what it is and I'm not that intrigued.
I also would have called Visual Studio Code something else. It's almost like they don't want attention from developers.
My opinion: they need to make him branding dictator for a month.
