Took panasonic 3 years but the GX1 is the GF1 upgrade.
After much deliberation I am now down to four lenses:
14mm f2.5 (equivalent 28mm) - Panasonic
20mm f1.7 (equivalent 40mm) - Panasonic
9-18 zoom f4-5.6 (equivalent 18mm -36mm) relatively slow aperture - Olympus
45mm f1.8 (equivalent 90mm) - Olympus

45mm not shown and thats a 14-42 zoom not the 9-18, but theyre similar sized.
The tripod is awesome replaced with a tech-trek ball head for travel.
There are also 2 long zooms that would be really useful: 45-200 zoom (equivalent 90-400mm) if you need to keep it compact, Or (the bigger higher quality 100-300) depending on what you are likely to be photographing
The 14mm is duplicated but for its size and weight - 53gms I simply cant leave this f2.5 prime behind.
total weight including; polarising filter, external flash (with off camera radio slave), 2 batteries, lens hood and intervalometer - 2.2kgs.
To put this into perspective thats the same weight as my Nikon fm2 with 35mm f2 lens film and hood.
It is incomparably small and it will all easily fit into your tankbag. The key benefit of the micro fourthirds system aside from smaller bodies are the much smaller lenses, whereas Canon and Nikon have still got to have larger lenses, this holds true with the Sony Alpha range, where the lens selection is not as advanced not anywhere near as compact.
Whats more there is a higher quality range - a 12mm f2 Olympus a 25mm f1.4 Panasonic a 45mm f1.8 Leica/panasonic as well as the 7-14 f4 Panasonic All for those with deeper pockets
Four Thirds | Four Thirds | Micro Four Thirds | Chart(Lenses) - lens range here.
I do have a Canon 5d with 5 L lenses to choose from but when it comes to travel - the Panasonic is the way forward, it is a little bit of a compromise, but is just so so much more convenient that I use it far more.
I initially got the Panasonic for a walking / hiking outfit, but its grown - its just kind of addictive.
However given any specific assignment or photographic task I will undoubtably take the Canon gear.
Good luck.
