Whilst I would love this to be true, I just don't see it. She'll be 70 this year and Christine is well out of it.
When interviewed in 2004 Christine ruled out recording with them as he thought she would get sucked back into the touring schedule.
I think - if she does fly to Hawaii - it will be to relax, maybe listen to these tracks, and then head back to Kent.
Oh and am I wrong or in 04 did Christine come to New York for her solo album promo? I recall her doing some interviews there, so she definitely has been back to the States (albeit not the west coast) since 98.
Sigh

wish she were coming back.
