This eWeek article indicates that Apple is now bundling developer tools with every Mac... not just with retail OS X:
Apple's Java team showed me their latest work at last month's JavaOne conference, where I discovered that the Apple Project Builder development suite (www.eweek.com/links) is now included on every new Macintosh. Previously, these tools came only with the retail version of Mac OS X, but now, they're available (though not pre-installed) on every new Apple machine.
OS X Dev Tools have always been provided free... but required a lengthy download if you hadn't bought Retail OS X. Bundling with every Mac would be a welcome addition.
