The 1D IV street price did drop a little in the UK, but it took a while. I seem to remember it retailing at around £3600 initially, dropping to around £3200 just before it disappeared. The UK street prices do seem to drop quicker than other markets, probably so that UK based sellers can stay relatively competitive with the cheaper grey market imports. The price differential between grey imports and local initial and RRP prices is probably larger in the UK than many markets. At the RRP, it is even cheaper to import from the likes of B&H and Adorama quite often on first release (assuming they're available), even with taxes, depending on exchange rates, so once freely available, the price drops just enough to make the hassle of warranty issues less worthwhile.
