N+1 Dilemma

Hello all, I’m fairly new here and already looking for advice :/ I’m in Latin America but I’m almost definitely moving (most likely to London) next year probably around this time, so I’ve resisted the urge to buy a new bike for a year now. The roads are not what you’d call smooth (though the scenery is brilliant) and my friends here mostly ride MTBs, so my stable is currently comprised of a decent hardtail and a cheap converted (42mm slicks) flat-bar commuter. But on a window shopping trip to a nearby shop, there it was: a BMC Granfondo GF1 Ultegra. They are so hard to find around these parts that I’d honestly never really looked. I seem to understand that it was a custom order that backed out, but it’s definitely brand new. It’s a 2015 model discounted to about £2,050 😀 It’s a bike I’ve been lusting after for a while but thought was a bit outside my budget. And to top it off, it’s just my size 😕

It’s not like I have the money lying around, but I’m likely buying that bike (or something quite similar) in a year. I’m no proper road cyclist and I’ve only done around 2,000 miles (though handily over 100,000 vertical feet) mostly (90%+) on “paved” roads last year, but I’ve wanted to get back into a somewhat proper road bike for a while. However I’ve held out for a year already and I’ve found it to be fairly tolerable (if you can excuse the sacrilege).

I know that it’s ultimately a personal call but any input is greatly appreciated. So should I just pull the trigger now and get the extra year of use of a great bike, or wait out an extra year for the disc-brake standards chips to fall where they may and in the process lose the not insignificant inconvenience of having to haul a bike across the Atlantic?
