If you watch the keynote video about AtScript you'll see that they describe AtScript as a superset of TypeScript 2. They add features they think are missing but are trying to keep the syntax wherever possible (actually they hope that much of TypeScript will be in a future EcmaScript standard and then they will follow that syntax).

According this [1] article from Microsoft, the TypeScript folks are coordinating with the AtScript folks.

TypeScript compiles out all the overhead, AtScript will need to leave at least some overhead so that it can support RTTI. The AtScript design acknowledges and borrows from TypeScript, ideally I would prefer it to be a superset so we don't end up with a lot of divergent dialects.

Looks to me like they are embracing Typescript. This is basically a superset. If I was on the Typescript team, I'd consider it a victory.
