Yes. If I had to peg DC's strategy, it'd be in this order:
1. Wally serves as a multiversal character leading up to another reset.
2. Depending on reception to above, it continues post-reset on an alternate Earth where Wally is a primary Flash.
3. When the above falls off, Wally goes away to Earth Limbo
4. Crisis 2025 Wally comes back.
I'd be surprised if that wasn't the game plan.
