What do you mean by this comment? The only splinter cell I ever played was the original one.
The "cool new thing" that major developers like to do with their products nowadays is essentially make them dumber, in order to appeal to a wider audience. The Splinter Cell series is a perfect example of this.
The original Splinter Cell game was a fine game indeed. I'd even say it was revolutionary for the stealth genre. It was a tough, but satisfying third person espionage game where you used a combination of nightvision, thermal imaging, and an array of gadgets that let you approach the objective how you wanted to. Controlling your movement was critical to your success, as you quite literally tip-toed through the shadows just inches behind your enemies. If you were sighted a certain number of times, then it would be game over. Period. (Death wasn't an exclusive means to end the game.)
Splinter Cell: Conviction was the latest entry in the series, and it marks where Ubisoft said "fuck it" and diluted the game to make it much easier; not to mention, much more uninteresting. There's no more nightvision gadget, as Sam Fischer now has the magical ability to see in the dark with his own eyes. The entire screen changes colors automatically when you become invisible. You can also somehow freeze time and insta-kill multiple people at once. Injured? No problem, just stand behind a corner and suck your thumb while the regenerating health kicks in. Oh, and all of the pistols have infinite ammo right from the start, in case they weren't already the best weapon in the game. Also, I hope you enjoy lots of pretty cutscenes. The entire game holds your hand. In fact, the very end of the game (without spoiling anything) is just a giant quicktime event and involves no challenge whatsoever.
I digress... Conviction was a fine game on it's own merits, but as a Splinter Cell title, it was disappointing.
What do I think of the new Hitman? Based on that video, I think it looks nothing like the style of the older Hitman games. In fact it looks like a reskin of Conviction, running on the exact same engine.
I hope that video isn't representative of the entire game, because it looked extremely linear and scripted. What made Hitman so great is how non-linear it was; there were so many ways you could approach an objective, and half the fun was planning out your moves, executing them, and if you made a mistake, adapting to it and moving on.
In this one, it looks like Agent 47 borrowed Batmans magical "detective goggles" or whatever.
Are you worried that a new developer will ruin it?
I never said anything about different developers. It doesn't take a new developer to ruin a series (see: Splinter Cell).
