Yeah, I definitely think they will since they seem to be headed in that direction with things like Xcode. It will make anything else irrelevant. I'd love to work on the design of something like that with an app developer, but there wouldn't be much money to be made. It would definitely be a labor of love and necessity. It's too bad a developer can't create a tool like that and get away with charging $30 on the App Store since the pricing is so horrible with professional tools for sale alongside iMessage sticker packs and Flappy Candy Farming games.
I mean, even Coda is talking about stopping development on things like Coda for iOS because they just can't make money. Meanwhile Apple is trying to get everyone to use the iPad to create stuff while letting the Mac stagnate without addressing the pricing problem on iOS. It also doesn't help that they only charge $25 for the darn app even though the Mac version costs $99. Although, knowing the App Store, that problem hurts them to have such a "high" price. I wish Apple would create a premium, curated section of the App Store for professional software that has high visibility and a minimum price point of like $30. That way you know you're getting decent software that has been vetted by a team of various creatives within Apple that tests things out. Maybe it could be an invite-only sort of thing, kind of like "Editor's Choice" but for a professional section. Either way they need to figure something out soon or the iPad Pro is going to struggle.
I'd love to use my iPad to do more creative stuff and development, but it's just not feasible. It would be great to kick back in a hammock and work on something beyond Lightroom or drawing, like a project building a website which involves editing a lot of images, vectors, and various files with preprocessors that need to all be published.
