UP can't hurt DWA because it has been released 2 months plus after Mv A was released. Mv A has run its BO both US and WW.
Up may help DWA however in UP has had to date strong BO and both films are showcasing 3D technology. Because DWA is committed to 3D tech and has made a heavy investment to promote it, any other films also having success using the 3D will only strengthen DWA as 3D is its only medium moving forward.
