Google is now rumored to announce an upgraded program of software support alongside the Pixel 6 and 6 Pro. This, apparently, might involve up to 5 years' worth of updates. Should this truly be the case, it will most likely be a bid to equal Apple and its panel of iOS upgrades.

I would prefer possibly the smaller Pixel 5a, but since it's supposedly based on the Pixel 4a 5G, I can't imagine it getting 5 years of support. 6.4" on super wide aspect ratio is just too tall for me.
