RSHS is alumni and pretty much everything he says is accurate, however a few things have changed over the years.
First of all Rav Ilson this year only gave shiur once a week on the yeshiva mesechta to the entire yeshiva, but stopped and started saying instead on a Sefer Hamitzvos shiur. Next year he might switch back and start saying everyday on the yeshiva mesechta. This year though he has started giving an optional iyun shiur twice a week on Ohalos, which my friends seem to enjoy, though not all attend.
Secondly, form what I understand, Rav Ilson is only as of now writing a sefer on Sefer hamitzvos, which will consist of the hakdama and the shorashim only.
Thirdly the bochrim now tend to be more right wing then previous years. They are by no means yeshivish. They mostly all wear hats and jackets, and I think even most wear white shirts. However the bochrim and yeshiva are very accepting, and no one is pressured in the slightest to dress in any particular fashion
Fourthly Rav Ilson I was told was a ben bayis by Rav Shneur (my friend was trying to convince me he is not modox at all), and stayed there every shabbos for like five years.
Fifthly I heard from Rav Ilson himself that he did not leave ToMo for hashkafic reasons. He said he left it when Bais split from ToMo, becuase he said when ever theres machlokes its better to stay away
