Before i heard anything about the current gen consoles, i had the presumption that MS would destroy everything with their epicness of third party locks, first party avalanche of titles(i assumed that was where all the effort and R&D was going after lackluster last 360 years) and lessons learned from their experiences.
It turned out different than i imagined, and i don't think i could have went back and told my past self without him having burst into laughter.
Sony had lost me for years after their early PS3 debacle and i didn't even really care all that much about what they were doing until the Slim came out.
