I think the R60 not being immediately discarded, plus the SC taking interest has given them pause.
The risk reward isn't good for them to enter the market right here, building up supply, then selling, then possibly being held liable for damages. If JT is being even half honest, then the profit margin for generics is terrible, so the decent chance of being left "holding the bag" isn't worth the small amount of profits they could eke out.
Losing these court cases though opens up the floodgates I'd wager.
