Upgrading from 2.0 Standard to 2.0 Professional

Our company would like to buy 2.0 Standard, however, we will eventually need 2.0 Professional later this year. Would the price for the upgrade from 2.0 Standard to 2.0 Professional simply be the difference in price between the two? For the 2.0 Professional, what will be the fee for continuing the subscription service and support beyond the initial 12 mos?

Thanks.

I am planning some changes in functionality and pricing of the standard and professional editions. The standard edition will work with all doctypes (both 'quirks' and 'standards-compliant') in IE and Mozilla/Firefox. The professional edition will support IE, Moz/FF and Safari (and Opera in the future). The price of the standard edition will stay the same ($395) and the price for professional edition will be $950.

AW 2.0 Standard Edition, developer license - $395
Additional 12 months of code updates subscription - $197.5

AW 2.0 Professional Edition, developer license - $950
Upgrade from Standard to Professional Edition - $555
Additional 12 months of code updates subscription - $475

I have bought the Standard Edition. So now I have 12 months of upgrades until March 1, 2007. So if I upgrade to the Pro version in June, will that include upgrades until June 2007 or will I only get upgrades until March 2007.

Thanks.

12 months from the upgrade date :-)
