I'm looking to get a nice HD cam with an separate dial for focus. I've found the Canon HF S100 can be bought for $650, but the replacement, the HF S200. is going out next month with a MSRP of $1000. I can't afford to pay $1000, but I can afford $650. The question is, should I wait for the S200 to come out and hope to buy it for about $650, or is the S100's price currently artificially low because it's about to be replaced? Should I hold out or go for it now? Which model?
