For a while I had both Bitdefender Internet Security 2013 and EAM 7 installed - I can confirm what Umbra said, the updates are being downloaded at the same time. The only difference I noticed, and this is purely subjective, is that the EAM update speed of BD signatures was slower than the respective Bitdefender update, which was no issue for me.
Back on topic, I actually expected Kaspersky to get the POTY 2012. During the year, Kaspersky and Bitdefender proved to be formidable competitors, which technically led the way, apart from a surprising, late Trend Micro surge. Had it been Kaspersky, there would similarly be posts about it being a hog, etc. And this drives home the main point of AV-C, like them or not, their methodology, any perceived bias, or not - this isn't so much about usability, nor is this focused on performance, it's first and foremost about protection.
As the MasterCard advertisement goes, for everything else - there's a product of the year for each and every one of us
