It's worth looking at who's at the helm. You don't make John Riccitiello[1] your CEO just to be bought by Microsoft, unless the price tag is extremely high (possible). He's there to build a huge business, plausibly bound for IPO.

Actually, Bioware/Pandemic made John Riccitiello its CEO just to be acquired by EA (but not before Riccitiello has resigned and joined the EA as the CEO again). Well, of course, this might have something to do with him being a partner in Elevation, which bought Bioware/Pandemic and, likely, invested in Unity as well (he had been sitting on the Unity board before becoming the CEO after being fired from EA).

Agreed. It seems likely Unity is on the IPO path.
