Something I noticed with NSMBU

I noticed this on Sunday when Nintendo showed that video on Wiiverse and showed us a small glimpse of NSMBWU.
But if you watch the video around 3:34 you can see the Castle in the far right of the level, way back in the distance, so could this mean it will be more like SMB3 where we have to get to the Castle at the end of the World Map to do a boss level?

My guess is that this level is still in the first world, but due to the background levels, you can still see Peach's Castle like the first level in NSMB DS. I doubt it would be like SMB3.

Could be. That would be neat. SMBW style maps and things would make me a little more excited for this title.

They did confirm that the Koopa Kids are back, so that could be entirely plausible.

I think that could be Peach's Castle, as it certainly looks like it. Who knows? I wish they did that, where as you progress; you can see the castle fade away. Also as you go through the later levels, you can see parts of the old level - I think that would be quite spectacular.
