I'm surprised there hasn't been any negative posts about Nexon here.
I'm not really familiar with EA, as I've only played one of their games (Alice: Madness) in recent years. However, after having played Vindictus (a Nexon published game) for the past year, I wonder if this is such a good idea. Nexon has had non-stop problems with hacking, connectivity issues, and some of the worst customer service I've seen in recent years. For example, it normally takes about 6 months to get back to people about account hacking, but issues with the cash shop are resolved in a few days. I'm not kidding or exaggerating at all - check their forums. This is just Vindictus. To my understanding, their biggest cash cow, Maple Story, has much worse problems.
What about the games they put out? While they are certainly start out strong, within a year the content updates have been lackluster...and that's putting it nicely. A couple new monsters you can fight once a day or three times a week isn't really what I'd call much content. Again, this is only Vindictus, but that is their biggest budget game they've released in years.
Do you really want EA to be bought out by such a company? Perhaps Nexon KR or JP isn't ss bad, but Nexon NA is simply awful. If this sounds like an improvement for EA, then both companies need to tank or learn how to treat their customers properly.
