Items #2 and #3 were provided in recent 7D firmware update 1.2.5. Item #1 will now likely also show up in next 7D update to provide UDMA-7 compatibility. The faster CF card, once it becomes available in smaller sizes (and more affordable cost), will likely improve read/write speed when using 7D in burst mode.
I use the UDMA-6 compatible SanDisk Extreme Pro CF card rated at 90 MB/s. Works great in burst mode. The 16 GB size isn't cheap, but at least it's available. Hopefully the UDMA-7 version will soon be available in smaller size.
The new SanDisk UDMA-7 card is currently only available in 128 GB size and 100 MB/s lists for $1500. Very prohibitive cost. This card appears to be motivated by video considerations rather than shooting stills in burst mode.
