No we cannot unless the speculated events are highly likely to take place. See my earlier reference to WP.CRYSTAL which says "Wikipedia is not a collection of unverifiable speculation. All articles about anticipated events must be verifiable..." You want to include something that is highly speculative in the case of the article from Holtz-Eakin. The truth is that all we know is that the board has to look for ways to cut the growth in costs. There is an endless universe of things that IPAB may come up as ways to do this. The fact is that WP simply should wait until IPAB reports and it is wrong to speculate what they may be. Sure, people can speculate but it creates bias if we include some speculations and not others. Its best for WP to leave speculation to other web sites. Its not encyclopedic to be selective as to opinions.
