Objects and blocks will only ever be in custom title packs I think.
But yeah, I guess it's a step in that direction.
It's cool how objects are independent of the building grid though. Actually allows for a lot more possibilities than was previously possible with blocks locked to the grids.
Also, TGYoshi said you can rotate objects in 15 degree increments (instead of 90 for blocks), which allows even more diversity.
I hear ManiaPark will probably do their own custom title pack and keep it updated with the latest and best objects.
Quite exciting.
