I'll answer to all these questions with one word: RDB. Remember it?
How many years ago Oracle bought it? Where is RDB now? Right, it is
still available under brand RDB:Oracle. As well MySQL will be.
Perhaps, because MySQL exists under GPL it can follow Firebird's way
- someone will create branch from the latest available sources.
But this way or that I wouldn't expect noticeable wave of migration
from MySQL to Firebird. They have very different niches.
