Will there be a minor Nexus 7 refresh in October?

I'm thinking of purchasing the new Nexus 7 (2013) for my fiancee to replace her Nexus 7 (2012) but I'm wondering whether it's best to wait or not, seeing as the Nexus 7 last year got a memory bump from 8 to 16gb (minimum) and adding a 32gb model. Is there any chance that Google will announce a minor refresh this year alongside the announcement of the new Nexus phone and Nexus 10 (2013)?
