For most number of updates, the PC Engine had many, and even more if you count the Duo systems.

PC Engine
CoreGrafx
CoreGrafxII
PC Engine Shuttle
PC Engine LT
PC Engine Duo
PC Engine Duo-R
PC Engine Duo-RX

Do these count?
Pioneer LaserActive
PC Engine GT
SuperGrafx
I'd count the last three, but not the CGII or RX. The TG-16 and PAL TurboGrafx are also unique enough to count as variations and not simply revisions.

There's also the Vistar, Sharp X-1 Twin.

Here's what I'd list all together-

PC Engine
CoreGrafx
PC Engine Shuttle
PC Engine LT
PC Engine Duo
PC Engine Duo-R
Pioneer LaserActive
PC Engine GT
SuperGrafx
Vistar
Sharp X-1 Twin


If counting silly revisions within models, like the HDG and non-HDG Model 1 Genesis', then we'll never be able to compare consoles since there are likely hundreds of different revisions across models of each console and most aren't widely documented.
