The OP's inbound traffic would shift to 100% over ISP2. Outbound
traffic depends on the routing policy in place at OP's network, and
could result in blackholed traffic in some scenarios.
Politically, ISP1 could contact ISP2 and/or its upstreams and request
that they stop honoring the announcement, but most ISPs will allow you
to announce their address space through another ISP for 90 days after
you leave, so this shouldn't be a major risk.
