I agree that he should use more 3090s, but I'm sure that he's not .. don't know the reason for that
the conversations between heather & mc, was the same lol if you remember the one in ToN between Emily & MC and also Sofia & MC.. both are the same.. he also has to animate it first before rendering & the lip sync animation as well, if he would have dropped that, then time would be consumed less.. despite doing all that i doubt he would make it in time for 15 days release, this includes testing game release version as well
edit; the most time consuming animation would be the first opening animation with Dr. nucleo & the next one of Melissa & MC when visiting Lillian .. I honestly doubt we will see these types of animations in coming updates.. it's just not possible, given the time
