Aaryn Flynn tweeted the following yesterday, and it got a lot of people excited. He stated that the engine looked great, which we saw in action yesterday with Battlefield 4. The tweet is below.
For everyone who's been asking after the #BF4 reveal, #DA3 and the next Mass Effect are also using Frostbite 3. It's awesome
