I'm coming out with my Gartner-esque probability ranking later today. Right now, nothing is confirmed, but the stock price and volume of said potential acquisition target is certainly higher than normal (volume is way up today, especially). Still, I simply do not have enough information from credible primary sources to make a call one way or the other. One thing I will say is that buy-out rumors seem to circulate every 12 months and each time it feels quite real. However, in this case, the potential acquirer has much to gain from this "rumored" move. But I've heard rumblings involving these two parties for years so who knows if it's any more real this time than in the past.
