It seems the NBA Jam license wasn't the only one EA acquired from Midway. Apparently EA bought a few sport licenses when Midway when bankrupt. Among them is NFL Blitz, which rumor has to be currently in development and the next game to follow this Christmas Holidays release of NBA Jam. Reviving classic games with modern graphics and updates seems to be going down well with consumers and if NFL Blitz can capture the addictive arcade gameplay of the original like NBA Jam has, it's sure to be a commercial success.
It will be a long wait though, don't expect to see NFL Blitz released before 2012. In the meantime, expect some more announcements in the future of past Midway sport titles getting a fresh release by EA.
