Web Player Splash Screen

The current version of the web-player (which is apparently just for developer use until the final version is ready) displays a "Unity" splashscreen while loading content.

Will the final version do this as well? And if so, will there be a way for Pro developers to disable the "Unity" splash graphics or replace them with something of our own?

The reason I ask is that clients who pay us to create online content with Unity, which they will then host on their sites, will in many cases not be happy to be hosting an advertisement for another company's product - even if it is a non-competitive one. Not allowing us to circumvent that Unity splash might limit our ability to use it in our work for hire.
