That's probably true.
However we can already see that the dev team is struggling to keep up with the patch release schedule...the patch content of today is noticeably smaller than the patch content of 2.0. Since HW we have have seen a decline in the content each patch receives....whether this decline continues will only come apparent during the 5.0 patch timeline. If the decline does continue then it's inevitable that eventually they will have to start pushing back patch releases, regardless of how many races we have....genderlock or no genderlock....
Personally I would much rather have quality over quantity...if SE need to push back patch releases in order to maintain quality content, then I fully support that! Otherwise we'll just end up with patches filled with shallow, throw away content....oh wait...
