I kinda agree - I don't use CP but I know there are people saying that the sales of the original products (SS shadows, original Lippie Stix) have declined. How they know is anyone's guess, but I wouldn't be surprised.
According to CP pr, the Sephora product range will stay at the original, affordable prices, so that's something. However, CP has also promised to maintain the same rapid product turnover.
I think in that sense, you're right, they will be stretching too far.
