Do think freshness is overrated...for most industry sectors having content posted a month later doesn't mean it is that much better...perhaps sports/software news being the exception. Things like history/science/etc...don't really need that fresh of content (with some minor exceptions). In fact, in many cases freshness just equates with being more chit-chatty/spammy and values quantity over quality. (eg facebook content which is very fresh but is typically poor quality)
Since these rankings are zero-sum, the question is who is going to lose with this '35%' change?
What will be interesting is if this freshness tweak helps determine page rank as this is far more significant. Given the '35%' figure I think it will... If fresh sites/pages get to pass more page rank this will create a huge cascade effect as child links of fresh pages benefit from this increase in PR...then the grand children links...and so forth...until a massive change takes place in the SERP's. If I'm right that having your backlinks serve fresh content will be much more important than having fresh content on your website itself...and having grandparent links serve fresh content is even more important and so forth...
