Can we expect full Laravel support out of the box?

Yes, there are third-party such as laravel-ide-helper I am using it for long but probably it doesn't support fully. Not having proper support for laravel slow-down the workflow, especially for beginners and/or intermediates who just jumped into laravel.

PHPStorm supports many CMS/frameworks such as WordPress that have wonderful support in the IDE. If you could add Laravel support out of the box would be a great advantage and make developers life much easier. Being an IDE leader you know better than us.
