With all due respect, you talk rubbish. Sorry a little rude but I sat trying to work out how else to put it
As mentioned, I personally bought a Silverback Phoenix 2011 model in November 2011 from Leewees Cycles in JHB for R4,500. At the time new ones were STILL selling elsewhere for R7k and a second hand one was on the Hub for R4.5k. And to back this argument up even more a mate of mine bought himself a 2012 Silverback Vida 5 for R5.5k from a shop in Durban a few weeks back. I cannot vouch for the usual price as most places online now show them as being out of stock. Of course, there is unlikely to be a proliferation of these old models as most shops to not keep vast quantities of stock but they are around.
Secondly, the middle of the year is not the norm to get the new 2013 range. I just spoke to a chap at Specialized, not a name drop but to check my facts, and he said this year was abnormal for them as there was a stock shortage of 2012 models due to change of importers into SA so they ran out and started getting the 2013 models in August on the low end bikes but the top end are still only arriving in now. I asked about the sale of 2012 models and he said with the stock shortages there is very little this year but it is usual to clear towards the end of the year. Remember he is just talking about Specialized but at the lower end this is probably even more relevant as more stock is held.
Finally, you will often find that it is not merely an upgrade of the old bike but a range may be discontinued, so the newer model might be totally different. This is particularly relevant with the proliferation of 29ers. The same chap just confirmed that they do still have some 2012 26" Specialized bikes in the warehouse that they are selling at R13k, normal price R17k. The same thing happened with my Phoenix. It is no longer part of the Silverback range so it is not as easy as saying the 2012 model was an improvement on mine. No doubt they would have had a replacement of some sort but not my same bike.
Apologies for being argumentative but when someone corrects something I say when I know it to be true I need to point it out
