Sonic X Shadow Generations?

So yesterday they announced the remake of Sonic Generations called Sonic X Shadow Generations. Ignoring the obvious problem with the name, the description of the video says it's an "all-new collection featuring two unique experiences." Does this mean that there will only be two Shadow levels? The only stages they showed were Final Chase and Westopolis, as well as the Biolizard boss. Doom's Eye was there but I'm pretty sure that was just Westopolis. Regardless I'd like to see more than just two extra stages...Maybe this time they'll actually add DLC stages like they should have when Gens originally came out?
