Reggie: Switch ports likely to arrive much sooner starting end of this year / next year, Nintendo has more to show in the weeks/months ahead

[LethalP]

Most multiplatform games will be late ports, unless they're small scale indie games. A game of the scope of Doom or Wolfenstein will always be a late port because most developers aren't willing to delay their PS4/X1 releases just to launch at the same date as the Switch version, which needs more time to make work on it.
