Some definitely will. Significant enough to assume they're not well-situated other-configs? Probably not. Even the most VIM- and CLI-oriented devs I know still prefer a familiar GUI for normal day to day work. Are they all going Ubuntu? Or Elementary? I mean, I welcome any migration that doesn't fracture the universe. But I don't think it's likely.
