It's not really "just after" letting out BW2. When it's released BW2 will have been out for one and a half year!
The starter designs are your opinion of course, but I quite like them myself. Hope the evolved forms will look good, too!
And unlike RBG and GSC, there's no actual reason except for fan service to make RSE remakes. :/
You can trade Pokémon from your 3rd gen games to current gen ones anyway.
