Dropping the V6 and sticking with one powertrain just makes things easier for exterior design. You can wrap that engine compartment tightly around the smaller powertrain and design your front end around it without the need to leave room for a larger powerplant.
My wife just bought a Kia Sorento with the 4 cylinder, when you drive the vehicle the big difference from the Rogue is this large, high hood that to me seems in the way and obstructs my view just a little bit. You pop the hood and see a little tiny 2.4L 4-cylinder in a big spacious engine compartment, and you may wonder why at first glance but it's obviously engineered to accomodate the 3.5 V6 - if they eliminated the 3.5 engine the front end exterior would likely have look quite different with a smaller engine bay.
With 4-cylinder engine technology there is no need for 6 cylinders in this size of vehicle any more. As an example, the Kia 2.4 GDI (Gasoline Direct Injection) in the Sorento makes 192 horsepower and 184 foot pounds of torque. This is roughly comparable to the early 2000's Pathfinder 3.0 L engine and the Pathfinder had around 500 pounds more weight. The Pathfinder was a pricey, very popular vehicle, but today's 4-cylinder technology equals and exceeds this recent V6, partiularly when you consider the 2.4 GDI gets at around 30% better efficiency.
I'm not necessarily recommending Kia, just using their 2.4 as an example because I have recent experience with it, all manufacturer's are bringing out amazing 4-cylinder power plants with the power of a V6 and efficiency of a small 4-cylinder, so why would need to even consider a V6 anymore in a mid-size vehicle? The big buzz in the truck world is the new Ford F150 3.5 EcoBoost engine which outperforms Dodge's 5.7 V8 in recent tests which evaluated hauling, towing large trailers, and overall "truck" functionality. The 3.5 blew the 5.7 out of the water. Just another example of smaller displacement doing the work of larger displacement engines of the past, and with fewer cylinders required.
I'm very excited to see the details of the next generation powertrain in the Rogue, I'm sure it will be spectacular.
