It is true. ISXEQ2 will not be updated until most likely Thursday night. I would suggest hanging out in IRC starting Thursday afternoon until you see me change the topic.
I may be able to beat evening raid times on Thursday; however, that will depend upon how complex/difficult the patch was. But, regardless, it SHOULD be done sometime Thursday night.
So, yes, you all will have to survive 2 days without ISXEQ2.
