I'd totally be OK with Hyrule Warriors complete, as missed a load of new content with Legends.
They would probably announce it only a few months before its release though, I hope FE Warriors will be successful as well.
If it happens in this FY then i think we'll get it Feb-match 18, to give fire emblem warriors a few months to sell. No point releasing both within 2/3 months, that's a disaster waiting to happen.
