This isn't one of those "the line is ending in 3 weeks" questions, but whether you feel like you could realistically see yourself just stop collecting altogether right now. I see a lot of collectors complain that the line is going on too long and they can't wait for it to end so they can cool out - it always makes me wonder, "then why are they sticking around?" Are you trying to have it all, and if so, would that keep you from leaving until Hasbro kicked you out?
The past few months of nothingness from Hasbro has pushed me to the brink, not quite as bad as Saga '03 where new figures didn't get findable from January until July, but darn close especially with so few figures I feel are necessary actually coming down the pike. This hobby doesn't feel as rewarding when it gets as frustrating as Hasbro's made it with supply issues AND Saga Legends junk clogging the pegs at the same time.
So I ask myself, could I walk away from it all? I'm not sure I could, I'm waiting to get the next round of vehicles, and I'd love to have the complete McQuarrie collection since it's something I've always looked forward to - though that seems almost hopeless now with McQuarrie Vader and Starkiller Hero being so difficult at this point to even hear rumors about. I suspect though that come the Grievous Starfighter, I could walk away and not look back, and that's a bad thing.
