The Flickr Blog has announced some updates to the Pro accounts, including a price change to $24.95 for a 1 yr. account. The other updates include a monthly upload limit of 2GB for Pro accounts and 20MB for free accounts (along with 200 photos available through the archive).
I always thought the price was a little high for me to purchase a Pro account but with the update in upload a month and the cheaper price I will probably end up purchasing one sometime this month.
