I have a question. You said that "the Passover holiday will no longer be observed." Passover includes eight commandments:

Excellent question.
The commandments of the Torah are eternal but
how we observe them is determined by the Sanhedrin (the 71 judges who decide halacha when we have the Holy Temple). The great Rabbinic sages (who are not part of the Sanhedrin) also have the power to determine halacha (Jewish law).
Where does the Torah grant these Sanhedrin judges and Rabbinic sages this authority?
Deuteronomy 17: 8-11:
ח כִּי יִפָּלֵא מִמְּךָ דָבָר לַמִּשְׁפָּט, בֵּין-דָּם לְדָם בֵּין-דִּין לְדִין וּבֵין נֶגַע לָנֶגַע--דִּבְרֵי רִיבֹת, בִּשְׁעָרֶיךָ: וְקַמְתָּ וְעָלִיתָ--אֶל-הַמָּקוֹם, אֲשֶׁר יִבְחַר יְהוָה אֱלֹהֶיךָ בּוֹ. 8 If there arise a matter too hard for thee in judgment, between blood and blood, between plea and plea, and between stroke and stroke, even matters of controversy within thy gates; then shalt thou arise, and get thee up unto the place which the LORD thy God shall choose.
ט וּבָאתָ, אֶל-הַכֹּהֲנִים הַלְוִיִּם, וְאֶל-הַשֹּׁפֵט, אֲשֶׁר יִהְיֶה בַּיָּמִים הָהֵם; וְדָרַשְׁתָּ וְהִגִּידוּ לְךָ, אֵת דְּבַר הַמִּשְׁפָּט. 9 And thou shall come unto the priests the Levites, and unto the judge that shall be in those days; and thou shalt inquire; and they shall declare unto thee the sentence of judgment.
י וְעָשִׂיתָ, עַל-פִּי הַדָּבָר אֲשֶׁר יַגִּידוּ לְךָ, מִן-הַמָּקוֹם הַהוּא, אֲשֶׁר יִבְחַר יְהוָה; וְשָׁמַרְתָּ לַעֲשׂוֹת, כְּכֹל אֲשֶׁר יוֹרוּךָ. 10 And thou shalt do according to the tenor of the sentence, which they shall declare unto thee from that place which the LORD shall choose; and thou shalt observe to do according to all that they shall teach thee.
יא עַל-פִּי הַתּוֹרָה אֲשֶׁר יוֹרוּךָ, וְעַל-הַמִּשְׁפָּט אֲשֶׁר-יֹאמְרוּ לְךָ--תַּעֲשֶׂה: לֹא תָסוּר, מִן-הַדָּבָר אֲשֶׁר-יַגִּידוּ לְךָ--יָמִין וּשְׂמֹאל. 11 According to the law which they shall teach thee, and according to the judgment which they shall tell thee, thou shalt do; thou shalt not turn aside from the sentence which they shall declare unto thee, to the right hand, nor to the left.
We are commanded to follow what the judges (the Sanhedrin) and the priests of the Holy Temple instruct us to do and we cannot deviate from their instructions. According to Chazal, these judges will change how we observe the current holidays. These changes will not contradict what is commanded in the Torah. The written Torah gives the judges and sages tremendous flexibility in deciding how a holiday or commandment is observed.
Therefore our celebration of the final redemption (the creation of modern Israel and the ingathering of the Jewish exiles) will become a far important holiday than Pesach.
