Yes if you could find a translation I would be interested as it is a confusing verb for me. This program I use "Rosetta Stone" if you've heard of it, just shows pictures and gives the words in Cyrillic Russian so most the time I find myself using Wiktionary or Google Translate to find the meaning of a newly introduced word and go from there. And the definition of sobirayus' just never seemed to fit what I had in mind for the sentence.

собирать (sobirát’) impf. — собрать (sobrát’) pf.
to gather, collect
to assemble
to convoke
(for a journey) to equip, prepare

В следующем месяце мы собираемся навестить своих друзей!

so in the original sentence; Next week we ...prepare... we gather, assemble... visit our friends. Just doesn't seem to fit which is why I guess there is no literal translation.
