I'm not overly worried now. Local impressions were that it was a bit better then SF4 from those who got it early.
Also- you could tell the SRK video they weren't too familiar with KOF, so they could have blamed things on lag.
I think at worst we'll get something playable , which is what matters. The point of netcode is that you can have fun at 5am instead of having to wait for friends.
I think that's what we're all looking for (at least I know I am). As I said in my previous post, the game looked to pause for a quick second. This could be lag or the video itself. If the game has playable online and no drops while in a match, then that's fine.
[Off Topic]I did play a lot of Street Fighter IV online and had a good experience. I never had a game drop or get to unplayable levels. The only worst instance I had was when I was playing someone in Spain. Other than that, the game ran fine.
I have the same expectations for The King of Fighters XIII online play. There's no need to overreact to just this video. Let's just wait and find out for ourselves when the game is in our hands.
