how Zynga is going to make money (advertising on DAUs) off the users that ALREADY PAID for the no-ads Draw Something app?

$250k/day with $0.99 per user == ~252,000 installs a day. That's almost 92MM installs per year. How many active users does App store have?

There will be plenty of places to cross promote their games. I'm thinking loading screens, contacts database,..

You're forgetting the in-app purchases. OMGPOP only makes a portion, albeit a minority, of their revenue from the initial sale.
