When do nextgen cards come out?

[Berg]

Well i was planning on buying everything for my computer this week but someone told me that the nextgen cards are all coming out this summer as well as new cpus. I need my new computer by the end of summer and will buy it if now if no major upgrades are coming in the 3 months to lower the prices of the older technology signifigantly. So my question is are the next gen cards coming out within the next 3 months and if so how much will current card prices drop when they do?
