Ok, connect the dots if you want...
First, Apple demos Xserve this week. During it's presentation, the part of the web browser was played by Chimera/Navigator. Obviously, the folks at Apple have become quite enamored with this project and saw it fit enough to use in one of their demos.
Second, since WWDC, Chimera builds have stopped appearing. For the last two months, a new build would be released once a week at least, sometimes with builds coming every other day.
Third, on the Chimera Mailing List, David Hyatt, the principle developer on the project announces that he's "on sabbatical" until July at least, and to not expect any builds for a while. Chimera is an open source project, but strangely enough David says this in his email to the list:
I'm on sabbatical until July 10, and since I'm the only one who can really
do Chimera builds (given the huge patch that exists only in my tree), I
doubt there will be any builds for a couple of months. I also won't be
working on Chimera again until July.
I could post the patch to a bug, but then someone will have to do the
(rather difficult) work of understanding how to merge the patch to the trunk
as changes occur.
So there you have the facts. Now, I'm not a conspiracy theorist, but let's just say I wouldn't be the least bit surprised if David's sabbatical takes place on the Apple Campus, with the fruits of the project being an Apple branded browser based on Gecko/Chimera.
Really, if Apple doesn't snatch David up it's their loss. Chimera is the best browser out there (although still incomplete), and with some minimalistic help from Apple, could really do wonders for the web browsing experience on the Mac.
