That's what they've been telling you, yes.
Of course the plan is to make as many people switch.
The question is how to do that without pissing people off?
By making them want to rather than to feel forced.
What's a surefire way to accomplish that?
Part one: tell them they don't have to switch.
Part two: give new characters more freebies.
Part three: Profit.
More insidiously: change an annoyingly large amount of small details under the pretense of "improving" the game, so it becomes a pain to keep playing the original (unless you completely isolate yourself).
Look this isn't rocket science.
