Is it possible to read the date set by a TV in order to determine which template to use for each resource?
I'm thinking of a list of events, whereby one template could be used for current events and another for past ones - i.e. if the end date (TV) is after today, assign a "current" template.

It is a little awkward to assign templates at run-time, since such resources can't be cached. It's better to use CSS, and then you can use a snippet or an output modifier to check the date and return the name of the desired .css file to use.
I'm not sure I fully understand - but maybe that's due to not phrasing my question clearly enough.
I was't necessarily planning on doing much more than altering the CSS class of the containing element. However, I assumed that assigning a different tpl chunk within getResources would be the obvious way to achieve this. I suppose what I'm less clear on is how feasible it is to measure the date value of a TV via getResources against the current date.

Ah. Not the entire page template, just the getResources tpl.
According to the docs, tplCondition only works with resource fields, not TVs. So I don't know of any way you could do it by TV.
Well, you could use an output modifier to insert some inline CSS in the tpl.

Well, after looking at the docs for output modifiers, you'd probably do better with a snippet in the tpl to output the inline CSS. It could be done with an output modifier, but it would be pretty complicated.
Actually, a custom output modifier (which is just a snippet anyway) would make it easier to deal with the TV value, instead of having to get the TV value in the snippet code.

Here's a snippet I called "setCSS" to use as a custom output modifier for dates 1 week ago:
<?php
$cutoff = strtotime("-1 week");
$tvdate = strtotime($input);
if($tvdate < $cutoff) { return "blue"; } // or whatever you want
else { return "green"; } // or whatever you want
return;
And the output modifier:
[[+tvDate:setCSS]]

You could use that snippet to output a classname if you wanted, then your .css file would handle the styling. The tpl could look something like this:
<article class="block [[+tvDate:setCSS]]">
etc...
</article>
Wow, OK, a few things to try and get to grips with.
The "setCSS" snippet as output modifier looks like it could be just the thing.
I assume that the $input argument is what's passed in from the tvDate placeholder?

All output modifiers have access to several values, including the value of the element it's being used on.

I don't think the TV filters will do what you want, it is used for determining which resources to show.
