Apple seeds Mac OS X 10.4.4 8G20
Apple last night seeded build 8G20 of the forthcoming update to Tiger to developers. There are still about five known issues (plus maybe newer ones and issues new for this build), but it looks like the goal of having 10.4.4 ready before the new year could be met. The combo updater will be a little over 110 MB once this is released, the delta updater that will be available through Software Update will be much smaller, of course (depending on the up-to-date state of your machine).
Development of 10.4.4 has shown progress on intel hardware as well, although build numbers are expected to vary between platforms while Apple brings the development efforts together. But feature-wise, by now the internal intel builds are up-to-date with the PPC builds (some executables still run through Rosetta on intel, though - this will probably stay this way until Leopard).
