Mark Cerny is the PlayStation equivalent. Seems a nice guy, but he's boring as fuck. Spencer is charismatic, he engages with fans on Twitter, he's very open and he's dragging Xbox out of the absolute hole they were in. I don't see what's weird about it.
They aren't equivalents - but if they were, there is still a massive difference -
Cerny has a 35+ year history in making games AND hardware, things like Marble Madness in 82 when he single handedly developed the game at age 18, single handedly saving Sega with Sonic 2, consulting on early ps1 and ps2 classics like Crash, Spyro, Jack and Dexter and ratchet & clank; through to halping to make the PS2 architercture, before leading the creation of of the PS4 and now PS5.
On the other hand Spencer is a business executive, with zero experience of making a single game, and his only experience in software is helping in the 90s with the creation of Encarta and other even less-remembered business-focussed things like Works and Money. He does seem to be one of those executives who do care about the consumer, and making sure that the games are the focus, but without the experience of actually making sure that the games being created are good.
Spencer's equivalents are either Herman Hulst in terms of Studios (and he has the background of Guerilla Games, and making Killzone and HZD), or Jim Ryan (who like Spencer is a business exec first and foremost, but unlike Spencer he doesn't really do much in the way of press conferences about the PS stuff, preferring to let people like Cerny and Hulst take the lead).
