I don't think this was the reason (or at least sole reason), but EG has been flying Justin to every goddamn tournament every weekend and he still keeps getting bopped 0-2 at Capcom Cup. He's obviously a great player but he hasn't had any sort of really high top level consistency in Street Fighter, at least not with all of the international competition which is hot and heavy at US tournaments now. He's a good face for EG, he gets their name out there and with a new Marvel game on the way I don't think they would have dropped him but I imagine costs had to be some sort of factor. Will be interesting to see where he goes, even if he did actually get dropped I'm sure he could get with someone else fairly easily although maybe not with the same terms/flexibility? Interesting times!
I barely even remember Rog competing much last year so no surprise there, and Momochi + Choco are doing their own thing (and good on them). Chris G wouldn't be a shocker for EG, he's a good name pickup and probably got picked up at much less than what they were paying Jwong if I had to guess. I'm curious who else they're picking up though if the rumors are true.
Edit: So they're also dropping their SC2 team (no surprise) but are ramping up their CoD team? Is competitive CoD actually growing at all? CoD seems to be cooling off in general sales-wise if nothing else, although I guess SFV makes the case for a game not doing super well in sales having a worthwhile competitive scene.
