This might have been covered before, but I didn't see it in here. I just wanted to let you all know that it is still possible to do bulk uploads in the new adwords interface. You could do it via the spreadsheet. You could find the spreadsheet interface under the keyword tab, in the drop-down menu that says "more actions". For the scripters like myself you should be happy to know that tab delimitation from a plain text file will paste in nicely.
The format that works is:
keyword[tab]enabled[tab]bid[tab]destination_url
hope that helps someone
