I heard they are considering dedicated servers. But don't really get your hopes up, it is a more of a "we are monitoring the situation" type scenario.
I've heard the opposite on the official forums. The forum admins are basically saying they are working on the problems but aren't looking into dedicated servers.
Personally I think the lag is absolute shit in this game. Its a fun combat system completely and utterly ruined by terrible match making, host selection and over all lag. I've played some 20 hours of the game according to steam, but I know a decent portion of that is trying to get people together for private matches or simply going in and out of games trying to find one with a reasonable level of lag (finding one with no lag at all is fucking impossible).
THQ need to fix this otherwise the MP is going to go down the shitter very quickly. They're already losing sales, if it wasn't for the piece of shit match making service I was planning on getting additional copies with my friends so we could play together, but as it is I wont be doing anything of the sort.
