I have heard Philips have hiked the price of these parts by 50% to existing
users in an attempt to persuade them to migrate to the 89V51Rx series.
Does
this mean the 89C51Rx series will soon be obseleted?

I don't know.
I never cared much about Philips MCU's. Mostly because when I worked with
them they couldn't even (or just) drive a single led. Every applications had
a lot of FET's or ULN's in it. Some MCU's from philips couldn't even drive a
ULN.
The second reason is only valid for some of the MCU and is also the reason
why I tend not to use NEC, is the lifespan. This is not long for most MCU's.
I like Microchip with their lifespan: It's relative long and if they throw a
MCU out of their program, which is always said a long time before they do
it, a pin and code compatible replacement is available.
