I've already said it internally but let me go ahead and say it publicly: as much as I feel for the around 1-3% of the people who will be left out when the switch happens, I think it is much more important to pave the way for future improvements and an overall better graphical gameplay experience. Technology advances at a fast rate and eventually everybody (of the the said 1-3%) will catch up. That is the great thing about open source and tech... they just keep getting better and better. On a side note, eager to see how far the capabilities of the engine are pushed and what the limits will be. Only time shall tell
