They were sorta advertized at the same time.
Before telling you what I thought you must know first that I generally stopped caring for Sony first party in the grand scheme of things this gen. I fell out of love with it. To me they're all designed around this idea of "move through the game to finish it", not just that it's linear but although some rooms can be hard to clear in The Last of Us or Uncharted or encounters in HZD or God of War, I feel like all Sony's games have this mandate of "Big, cinematic, cutscene" stuff and the focus of production is so laser-focused on that, that the gameplay becomes less than the game's "Main idea". Playing through their PS3 lineup, Uncharted, InFamous etc. it's enjoyable but it winds up as a middling experience in hindsight because it ended up feeling like "just going through the game and finished it..." without any moment of gameplay making you go "THAT was cool!" InFamous had it the most. In Uncharted it was scripted and since then I feel Sucker Punch has gotten more "cinematic" which isn't improving their games.
So I've liked everything previously Sucker Punch did, but back when InFamous was new I was still impressed by graphically advanced games with fluent mechanics. Nowadays we don't just standardized fluent mechanics and awesome graphics, we got games like Dark Souls to advance the impact of combat and we also got games like Mass Effect or Witcher where they combine relatively "cinematic" flavor with deep player impact on the flavor and flow of the cinematics. I find there's too many smoke and mirrors going on with Sony's first party lineup this gen, and that's how GoT came across too.
So the prospect of GoT being a somewhat sandboxy but linear, "do a bunch of quests but especially the main quest" game that lifts the "Fear Takedown" idea from Arkham Knight to a T, and also probably has functional and slick but ultimately not that advanced combat design... it's hard to even be impressed at that point, and I wasn't. Graphics crossed some kind of threshold for me last gen. Now I'm just used to everything looking amazing and it's not the selling point anymore.
If Sekiro hadn't been unveiled I'd have said "Oh cool!" because of its feudal japan, shogun-ish theme, but Sekiro also had a lot of that albeit in a more stylized way, but because it's a more advanced
video game I just don't really care for GoT despite being the second last biggest thing in the whole first-party lineup.
Be honest, topping Sekiro's swordplay is really hard. At some point i felt like a real ninja/samurai while playing Sekiro. I hope GoT will have same/similar swordplay.
Hint: It won't.
And it will have Fear Takedown straight outta Arkham Knight.
EDIT: bad demonstration but it goes the same way. Drop from below or above, slowmotion, pick up to X targets to chain strealth takedowns. AK innovated, now we're seeing games ape it, and it means GoT is focus tested to death.
