TW 3 had its issues, both in (1) story telling and (2) gameplay; how big or small those were, it depended on how much you're willing to turn a blind eye to the whole "target a bigger audience!" approach.
1) You're forced into the relationship with Triss through the series (as in getting intimate), although you may definitely don't want that knowing/hearing from others about you and Yen. Then you have the witcher, which at the end of second game, not only is pretty powerful by his own gains, but gets his memories back, only in the 3rd installment to "forget" potions and skills which AGAIN you have to learn them - more funny when Ciri knows to make a werewolf potion due to her teachings with Geralt and the other witchers, while Geralt has to learn the recipe one more time...
2) and this is related to 1st point, guards and other NPCs are far too powerful and would nullify the need of a witcher (and Geralt should have been the best swords fighter in the kingdom) - and this is also a problem at a bigger scale, with enemies being higher lvl and hard to kill "just because". You can also kill some of them when the game carefully puts you in such a situation during a quest or two, but other than that... Godlike, more so at lower levels - although again, you were passing through them like a hot knife through butter during the past 2 games. At least Cyberpunk is the 1st in the series...
Now, if they take the same approach in the gameplay department like in TW3 and other style of open games (aka, grind fest), firefights and gameplay in general could get boring after the novelty passes: if what you need to pass an obstacle is just to get a higher skill on "handguns" on the progress by the "gun" way (instead of stealth or technology paths), so bullets get a magical 20% dmg output - Fallout style.
I do hope they've taken a more "realistic" consideration and the world behaves more natural (doubt it, but hope still!)... However, in the end, more likely the story telling and characters will be great, which is all it needs for good sales - and a fun playthrough, i guess.
