Since Microsoft was working internally on the raw search optimised Prometheus model since mid 2022, and Google did not show any chat results showing sources. My bet will be that Google won't even show sources below Bard results even a year from now. And this difference alone and with Microsoft already starting the first rollout of Bing Chat, I feel Bing will have gained a lot of marketshare in a year. Bing can only win and Google only lose with the current marketshare numbers.
