So from the few comments here, can I take it as the NeoPDP technology is mere marketing fluff?

Higher contrast ratio, brighter, slimmer panel, saves energy.  The NeoPDP in the G10 is definitely a step up from the S10, no doubt.  My concern is whether all these 'improvements' are worth/significant enough to cough up the additional RM2,000.

as a matter of fact, 95% of the customers will still choose the new model instead of the old model before making decision. we just cant deny it.

other than that, the customers will look at the price (primary) and also the features (secondary). the customers dont take the cheaper components issue into the consideration

just an example, Pioneer KURO has a very high standard spec and also at a premium price, how many customers can afford this budget?

and now P42G10 is the closest rival to Pioneer KURO (ever since 50PY850 series) with a more reasonable price, this is the reason why Pioneer has to close down its Plasma panel production after this year due to pathetic market shares loss to panasonic since 2008.

for those who are looking for the best plasma tv yet at an affordable price, P42G10 is highly recommended.

there is a minority of the customers who will still demand for the premium models

the latest Sony model which is 40" and its price is nearly RM20k. this price is 3x more expensive than P42G10k. sony enthusiasts will still rather buy this model instead of panny G series. SONY, LIKE NO OTHER. 

fyi, by november, panasonic malaysia will launch Z series 52" ultra slim NeoPDP at RM20K ++. this model is the one appeared in Sunway Pyramid during the panasonic launching in April,  8.8mm thickness
