The last time I looked at webhosting.info it displayed Netfirms having around 330,000 domains hosted.
It was hard for me to find any reliable data to guage how many domains Bluehost, Justhost, and the other EIG companies have. But a rough guesstimate would put Bluehost/Hostmonster at 2 million, Justhost at half a million, and EIG at 1 million which would bring EIG up to a total of 2.5 million domains hosted. Adding Netfirms to the equation would put EIG around 2.8 million domains hosted.
So who is EIG going to target next? Dreamhost? Lunarpages? OVM.net? Mediatemple?
Godaddy was on the market a while back. Wouldn't a merger between Godaddy and EIG be an interesting mix?!
