2016-10-27 - Bitcoin Core version 0.13.1 released
2016-08-23 - Bitcoin Core version 0.13.0 released
5 versions in under 9 months
0.13.1 - 0.14.1 = 4 versions in 7 months... im pretty sure that it wont take a year to get everyone to download one version
id say let it get 80% and then have just six month grace.. not a dang year.
