As far as I know, Apple has never confirmed in writing when they will
stop or have stopped updating earlier systems. It can only be determined
from anecdotal evidence, and the cutoff appears to vary between
components.
The usual rules (as determined by observation of past versions) are:
1. Minor version updates cease around the time the next major version is
released (e.g. 10.6.8 came out shortly before 10.7, 10.5.8 shortly
before 10.6, but 10.4.11 was shortly after 10.5).
As we are in the transition zone after the introduction of 10.8, it is
not clear yet whether there will be a 10.7.5 update, but there have been
rumours citing a developer seed of that version. If 10.7.5 is released,
it would probably be the last minor version update for Lion.
2. Security updates covering a wide range of system components cease
around the time the second subsequent major version is released (e.g.
10.5.8 got security updates until shortly before 10.7 was released,
10.4.11 got security updates until shortly before 10.6 was released).
We won't know whether Snow Leoaprd has stopped getting security updates
until Apple releases the next Lion update. If 10.7.5 or a general
security update for 10.7.4 is released, and there is no corresponding
security update for 10.6.8 at the same time, it probably means Snow
Leopard security updates have ceased.
If there is a security update for Snow Lepoard then that might be the
last one, but we won't know that until the following security update is
released for Lion.
3. During the "security updates only" window, Apple may also release
other minor updates to specific components.
4. Some components which get updated independently like Java, QuickTime,
Remote Desktop, AirPort Utility and Safari seem to have their own
completely arbitrary cutoff cycles. Java and QuickTime often stop
getting updates before the final security update. Safari has sometimes
been updated well beyond that point (for 10.4.11).
When Safari 6 was released for Lion, Apple not only didn't release it
for Snow Leopard, they also pulled the page which allowed you to
manually download Safari for Snow Leopard, and pulled the Software
Update images which let you update to Safari 5.1.7. At present, the last
version of Safari avaialble for a fresh Snow Leopard installation is
5.0.5, which came as part of the 10.6.8 combo update.
This a puzzling situation and it may be temporary while Apple is working
on a new Safari update for Snow Leopard, perhaps a version 5.2.
5. iTunes supports older systems for quite a bit longer than anything
else from Apple, sometimes a year or more after security updates have
ceased.
I expect iTunes will drop support for Leopard when the next major
version is released with support for the new iPhone model, probably in
September.
There are rare exceptions where there is a "late" update targetting a
specific issue. The main one which occurs to me is that Leopard got its
last general security update in June 2011, but then had one-off updates
to deal with Flashback in May 2012.
Apple may of course break the pattern and do something different. We
might yet see a 10.6.9 update, or a targetted Snow Leopard update to
remove the vestiges of MobileMe support, perhaps even add some iCloud
support (unlikely in my opinion).

Don't know yet. Safari on Snow Leopard may yet get another update, and
if so, it could be updated for another year or so (based on what
happened with Tiger, but not with Leopard).

Those are not likely to be updated further by Apple unless there is a
general security update.
I'm hoping that Snow Leopard will get at least one more security update,
and based on usage figures, Apple may need to consider releasing Snow
Leopard security updates for several more months.
