could the Dubai bubble be about to burst.
Not a question of 'could' but rather 'when'. Even the IMF have recently expressed their concerns regarding Dubai.
You can't polish a turd and especially so when you try to make that turd out to be a shining diamond! An economic slowdown in some shape of form in Dubai is 100% guaranteed as recent growth simply isn't sustainable. Sadly fuelled by greed!
As for a future 'crash'.......... hopefully not!
