I’m very keen on the improved write speeds but you should note the fine print.

‡‡ Figures based on updated firmware, ISO 100, Standard Picture Style and with 8GB CF memory card (normal speed). Figures in parentheses apply to 128GB UDMA 7 CF memory card (high speed). Note: UDMA 7 CF memory card read/write speeds are not fully supported with the EOS 7D Digital SLR camera, if using UDMA 7 memory cards, the read/write speeds will be equivalent to UDMA 6.
Also the GPS is something big for me, once you start Geotagging you won’t want to go back. The only problem I have with the GPS unit is its location, you cannot use an external flash. I’m looking forward to the review from Bryan.
