Toyota is opting for similar interior styling in their almost all vehicle line-up, Vitz 2011 and Camry 2012 have almost same interior as this.
About the rear it looks ugly current one looks much better and simpler, this one reminds me of Toyota Etios 
Interior and Front are not ugly but not great aswell, i guess it will take time to get to like it.
And finally the Next gen corolla will be releasing in Pakistan by the End of 2014 or in the beginning of 2015 with exactly same interior but with little bigger sized and better looking exterior.
