Let's be real here. You can't even make a circle in GIMP without jumping through various hoops. Right now, the hurdle for those professionals is just the name, but wait until you see when they actually try using the tools. They'll happily pay for Photoshop once they realize that what they wanted after all was just a free Photoshop. This is quite a different angle I am arguing from, but it's my pragmatic side. I believe GIMP should maintain it's current userbase that was earned through over 20 years of hard work under their current name, instead of chasing customers that will unlikely appreciate their project anyway.
