I'm very likely to get an R1, but if it winds up having =<24mp, then I'm not going to bother. I am very impressed with the A1, but have too much glass in the RF system to consider it, so I'd just stick with the R5s if the R1 is lame.
Things I hope this pushes Canon to do with its R1:
- All the stuff the R5 has +...
- 45mp + (really this was my big complaint prior to the A1)
- Better heat management for longer internal high bitrate video
- Antiflicker in electronic shutter, without lowering frame rate significantly
- Faster flash sync
- Pixelshift hi-res with in-camera processing
- Double CFexpress Type B cards
Things I hope it doesn't push Canon to add:
- 30 fps stills. Give me variable rate up to 20 fps, and I'm happy.
- Type A cards
Sony has a long tradition of timing release announcements (at least ones that aren't themselves tied to an actual shipping date) to imminent releases of competitor's offerings. They very much like to steal others' thunder. This might portend that they think Canon is going to announce the R1. As this will be launched in March, there doesn't seem to be another reason to have this sudden announcement.
