they don't need to tell us anything about a patch coming.. nor whats in it, it's a courtesy.
It's not a courtesy to bring a title you released to a playable state.
It's a requirement on release day.
If that isn't the case there need to be fixes on the way as fast as possible.
It's also not entitlement to expect your purchased product to function properly.
Not even whining or anything. I'm a big fan of Bethesda games, and I know what a mess they usually are in the first weeks/months, but the point still stands.
