I currently have R3, and I feel upgrades for R1 don't justify the upgrade price. The biggest feature for me would be the pre-capture, but that alone doesn't justify the upgrade. I have big event in May 2027 and I'm quite sure I'll upgrade before that. There's another big-ish in July 2026 so upgrade before that would be nice but before May 2027 for sure. If R3-2 delivers good performance and pre-capture, I think more likely I'd get that one than R1. If there's R1-2 coming within next 12 months, that'd be interesting but I'm very doubtful we'll see R1-2 before 2028
