Exactly. The Bloodborne team is not the DS2 team either. Miyazaki wasn't even involved in the development of DS2.

You really believe in mythical 'A' and 'B' team? It's just marketing, not more.

Apparently, "more" means "other".... Not really sure what you're trying to say :S

You do know that Miyazaki was not involved in the development of DS2, which is very significant. So unless you can actually prove that there were no two teams from From Software, then.... yeah...

Looks pretty great, March couldn't come sooner.

The game looks fantastic. Plus its exclusive. This makes the whole deal sweet.

The game was inspired by Latria.

Looks like a gatling gun

the mere fact that they released a game in early 2014 and will release another one in early 2015 means that there has to be 2 separate teams, although a sizeable staff probably has been moved to bloodborne after completing DS2

The game might have something like randomly generated or changing dungeons:

The underground of Yharnam, vast ruins built over several levels. They’re terribly old, perhaps made by people according to their purpose. They appear to be a grave, or maybe just a place where something rests.
And, these ruins, it is said they change appearance depending on the person that sees them.

"it is said,these ruins change appearance depending on the person that sees them."
That's cryptic... Could be aot of things. Considering the player isn't the only one that would be seeing them. Enemies and online players perhaps.. with world events.
