So by April it will be 6 months since 6.5 (I barely even count 6.55 as a patch here compared to 5.55 that gave us Zadnor or 4.55 which gave us hydatos) and about 4 months till 7.0, if you are super generous and call 6.55 a patch it’ll still be 7 months from 6.55 to 7.0 and at the time of 6.5 releasing it’ll be 4.5-5 months since 6.4
You are assuming there wont be a patch in between. I am fairly sure they are well aware of the possible gap. Have a little faith, yeah?
