They're trying to get as many people to take the gamble and buy the Abasin pass before the announcement.
Getting people to buy their pass immediately before devaluing it by adding Ikon doesn't sit well. I expect more of A-basin.
The more I think about it the more I hate the idea of A-basin on Ikon. Even with 5/7 days, I don't believe it will resolve the reasons they left the Epic Pass and many of their core customers heading for the exits.
A-basin, Mary Jane, Copper on the same pass will just be too attractive to front rangers. RMSP was extremely popular with just WP and Copper. 5 days at A-basin will be plenty for most and allow Mary Jane hordes to migrate to A-basin and put us back where we were with A-basin on the Epic Pass.
I love MJ, but there is not enough advanced lift capacity and steep terrain for the demand, and I don't want to see those folks filling the parking lots at A-basin. Copper, fortunately, has the advanced/expert capacity and is adding more with the Tucker lift. Copper also has I-70 and the tunnel as a limiter to front range hordes, which I'm perversely growing to appreciate more and more each year.
Save A-basin and Copper by throwing MJ to the wolves.
