Portugese will be a seperate update they won't even mention it on Runescape.com it'll be on the portugese RuneScape site, just like french was, german there was a topic because it was first ever multilanguage release. As for todays/tommorows update (strong feeling its today) you won't be disappointed, it's a summer release which are always big, and has had a weeks preperation for release, which won't be a tiny update, they're creating hype by posting on twitter about this, because it makes people think hard about what it could be, it's most definately MA, maybe bundled updates, MA, Zanaris etc. By this time last year we already had Summers end quest + HD release, year before was Godwars I think (although that was august).
