The upgrades are small but they make it a more balanced phone. Anybody owing J5( 2015) doesnt need to upgrade but the package is good for new buyers.
As always, it comes to the price. If they can price it at the J5( 2015) pricepoint( i.e. 12k in India), then it would be fantastic. However I doubt it, and expect it to be priced a little higher. Something like 13k would be a good price.
