Batman Beyond Movie After The Dark Knight Rises? (includes Batman Beyond Concept Art)

Where will Warner Bros' go next? It is already well known that they want to reboot the franchise in order to aline it more with the planned 'Justice league' movie. If they wish to do that, they could easily do a 'Batman Beyond' movie as well, because when they watch the series, the original Batman is part of the Justice League, and he becomes the mentor to the new Batman, who eventually has a run in with the Justice League of that time. So they could do a new Batman film series, one linked with the Justice League, and a 'Batman Beyond' film series set in the future, far after the events of the Batman and Justice League movies. They could potentially create a DC Universe that matches that that Marvel has created. This could then lead on to a 'Justice League Unlimited' (the 'Future league' era ) movie. It could work.

Here's some concept art/posters by Guy Bourraine Jr.

They look pretty good to me.
