Just Completed SMG 1, and noticed a hint for SMG2 in it. (spoilers)

So I got me 120 stars, owned bowser in the final stage and watched as the credit rolls. then a scene showed Rosalina saying "i will watch over you" before she flies off into space with the space ship. But notice where she flys torwards... if you look carefully it is the 2d map world that will be used in SMG2. not only that but a luma is left behind. Is this the orange luma?

Any one else notice this.

now for luigi time!

I don't remember seeing that but it could be I guess. I do love how Nintendo adds little things that make us wonder

Are you talking about this?

Nope, I had never noticed that. I think you are reading too much into that.

well i guess this could be a little hint to SMG2
