Don't bother waiting for X-E2 la. That's around 1 year more. Even the X100 still makes amazing photos today that trashes even full-frame DSLR. What more information you need?

If you want the flexibility of changing lenses, just get the wide-angle converter WCL-X100 for X100/X100S, around RM 1k. I'm tempted also but price is a bit high.
So far nope, but haven't really fully used it.
Got my custom shutter buttons for the X100S and X-E1 from YL Jaya 33 Accessories Shop. Even got my red original Artisan strap from there. Awesome place! I think they are the only shop retailer in Malaysia that sells them.
