A ticket to the Fortune Most Powerful Women Summit

The just released Fortune Most Powerful Women list includes more Fortune 500 CEOs than ever. And next week's Most Powerful Women Summit includes plenty of them--Indra Nooyi of PepsiCo (PEP), Ellen Kullman of DuPont (DD), Pat Woertz of ADM (ADM), Denise Morrison of Campbell Soup (CPB)...plus one guy who manages to secure an invitation to the Summit every year. Warren Buffett. Fortune senior editor at large Carol Loomis will interview the Berkshire Hathaway (BRKA) chief Tuesday morning.

You can watch Buffett and Loomis, as well as the entire main-stage program, for free by registering for the Virtual Summit, here.

This year's Summit participants include a record 30 of the 50 women on the MPW list. I'll be interviewing Facebook COO Sheryl Sandberg (No. 12 in this year's rankings), media-empire builder Chelsea Handler (one of Fortune's featured women entrepreneurs), and Barbara Bush, the former President's daughter who now runs a world-changing startup called Global Health Corps.

We'll have provocative panels and one-on-ones with IBM's (IBM) Ginni Rometty, Gilt Groupe's Susan Lyne, financial services analyst Meredith Whitney, Gloria Steinem, actress Glenn Close, and AOL's (AOL) Arianna Huffington. Handler will interview Huffington. The two women have never met, but their phone conversation last Saturday suggests that this will be a must-watch session.

So tune in next Tuesday and Wednesday--and if you want a peek at what this hot-ticket event, now in its 13th year, is about, watch this:
