Everyone getting Alex for free is nice, but I'm confused about what's going on at Capcom to make them have to put out Alex two days after the patch. They must be working on a really strict time budget.
Maybe this gives them one day to retract the first patch before releasing the second one?
Theoretically, they could still release the store/alex and rollback the first patch if anything goes wrong, since it seems the first patch is orthogonal to the store/alex.
They haven't mentioned daily challenges since February, and they've dropped any mention of it in the recent patch updates. My guess is that it'll be coming whenever the Zenny store is ready.
They may not want to add even more ways to make FM if the Zenny store isn't up so early.
Then again, the monday patch will include trials mode, which is another source of FM, but I guess the daily challenges are even farther away.
They could want to wait until the Zenny store to see if the balance of people buying with real money vs people buying with bison dollars is worth upsetting.
