Here it is:
- Storm states that the players weren't officially notified that WoT is now running on a different engine because the new engine is not yet completely implemented. Once it is, the players will learn of the changes;
- New engine will partially support multicore mechanism;
- There is no ETA for full implementation ("so that players don't whine");
- The new engine will at first increase only performance and quality of various effects such as lighting and shadows, later the entire WoT content will be reworked for the new engine, it will essentially be a new client.
