Yes haven't said anything about new studio material (other than the standard "we won't rule it out") and that is probably because Jon Anderson always had a huge role in the writing. Mostly lyrics, but also more of the music than many realize. Howe, Squire, and White also contributed to the music, of course. Wakeman tended to work directly with Anderson on some things, but other than that, he mostly showed up once the songs were pretty well formed and figured out some keyboard parts for them.
We've seen some evidence that Howe, Squire, and White have great musical ideas, but Anderson was always the one who pulled it all together, and as he's shown no interest in returning to Yes, I would not expect any new Yes studio material.
And before anyone mentions Drama... that was a rather different situation. Howe, Squire, and White had a lot of material already worked out, as did Downes and Horn. They combined their material and talents in what turned out to be a pretty good album IMO, but again, it took collaboration and a lot of work. I would not expect the current Yes lineup to even be interested in the amount of work a new studio album would require.
