OS X Updates finished as follows:
10.0 - 10.0.4
10.1 - 10.1.5
10.2 - 10.2.8
10.3 - 10.3.9
10.4 - 10.4.8, so far.
make of that what you will. 10.4.11 has never been ruled out as a possiblity, and 10.3.10 was rumoured, i seem to remember. however, there are at least 3 months before leopard.
Then again, MWSF is rather "un-businessy" when looking at past product introductions by Apple... More the iTV/iPod/iMac/iLife stuff. 10.5 will surely get its big intro (release in March sounds reasonable, but they _could_ make an early splash if they wanted...). But this thread's about 10.4.9 and whether there'll be one. We don't know. There have been no rumours about it yet. No builds seeded AFAIK. 10.4.8's just been released. Any specific problems with it, or why is it you ask?
