What credibility are Nikon or Canon missing? Both companies have a level of brand recognition unrivaled in the Photography world...? Only in recent years has Sony and maybe Fujifilm developed more respect due to some of their advancements where Nikon and Canon have lacked.
Their DSLR's are market leaders still. Again, only in recent years have Mirrorless cameras have started to catch up with the DSLRs Nikon and Canon have been releasing. Based on current rumors, both Canon and Nikon are supposedly working on their first serious Mirrorless cameras to compete with the likes of Sony's A7 series...
EDIT:
Personally, I would avoid any camera that had Google integration built in. Part of the reason I still carry around a DSLR today is because I like knowing that the photos on my camera, and then stored on a local HDD at my house. I don't think I'm alone in this thought either. Computational Photography is cool and all, but I don't need to provide all my photos into a server farm to be analyzed.
