Below is a table that shows how many minutes of footage you can record on a P2 card. There is now a 64 Gig card that runs around $900 so you can finally get 1 hour of full quality video per card!! For the run and gun type stuff I plan to do, I'm thinking I'll need at least 2 x 64 Gig cards or I may even go the AVCHD route :( Perhaps the answer is to shoot in 720p?

Difference between P2 A Series and P2 E series?
Panasonic offers two lines of P2 solid-state memory Cards, the “A” Series and “E” Series. The chart below highlights their similarities and differences. The main difference apart from A cards being double the price of the new E series is the service life of the card 5 years VS 100 years. But 5 years of continuous use seems enough to me and in 5 years we'll be on 512 Gb cards for $400 right!
