Rumour - Zynga's IPO set for Friday

Kotaku cites an anonymous source as verification of a widespread rumour that Zynga will finally make its initial public offering this Friday. The source reports employees will attend meetings before the end of the week, to be briefed on how the IPO will affect their positions. The social games publisher recently lowered its valuation from $10 billion to $7 billion, but expects paid subscribers to rise in the wake of going public. Zynga currently holds the top five chart positions on Facebook's daily users tracking.
