Excerpt from Google’s blog post:
Today we see an even greater opportunity to make Pixel smartphones available to more people in India, and are very excited to announce our plan to manufacture Pixel smartphones in India. We intend to start with the Pixel 8, and will partner with international and domestic manufacturers to produce Pixel smartphones locally. We expect these devices to start to roll out in 2024, joining India’s “Make in India” initiative.
I don’t know more than you on this but while in the blog post they say they’ll start with the Pixel 8, I don’t see why they wouldn’t do that for future Pixel lines too if it ends up working for them with the Pixel 8 line. I don’t think they’ll abandon their manufacturing in China though, I think they’ll use the new India supply chain to diversify a bit and probably address the Indian market with phones that are a bit cheaper (it could be that they get some tax advantages there + Indians could buy it without any import tax which should mean a lower price).
