We explore the evolutionary diversity of the massive protocluster NGC 6334 I using comparable sub-arcsecond resolution (~600 AU at 1.6 kpc) imaging from centimeter to submillimeter wavelengths. Using the recently upgraded Jansky Very Large Array (VLA) at 6 cm, 1.5 cm, and 0.7 cm and the A and B configurations, we have detected all four members of the massive millimeter protocluster NGC 6334 I in at least one centimeter wavelength. We also find a new continuum source (JVLA1) detected only at 6 cm which coincides with the group of water masers located north of SMA1. Combined with Submillimeter Array (SMA) imaging at 1.3 mm and 0.86 mm, we analyze the continuum emission from each object, disentangling the dust component from the various types of free-free emission where possible. We briefly summarize the relative evolutionary state of all the objects in light of these latest images of the continuum, molecular line, and maser emission.
