Incredibly Scant Details Regarding Iron Man 2 Cast

Apparently an Iron Man 2 casting call sheet went out, with the following roles:

30s, Eastern European, brilliant, gritty…

20s, beautiful, speaks several languages fluently and is equally proficient in martial arts…

Russian, 20s or 30s, at least 6?2?, able to perform own stunts, has the build of a MMA fighter…

And from that, Coke and Comics and Newsarama surmise that both Black Widow and Crimson Dynamo will be in the sequel, assumably as Female Lead and Bruiser. So who’s the Male Lead? Have they decided to make the Mandarin a generic Eastern European guy? If so, will he still have magic rings? Will he be named after another fruit? Your preposterous speculations in the comments!
