In my group people just carry on playing whatever they played - there's no
GW shaming, no hate, no whining, no mass leaving. If someone starts playing another game, it's not because they dropped
40k, it's mostly because they thought it was cool and wanted to try it out in addition to their
40k/WFB armies. That's how I started a Warmachine army and I'm somewhat inclined towards giving Dystopian Legions and Dystopian Wars a try if anyone in my area will be interested in those games(nothing worse than starting an army for a game noone plays in your group!

).
So while the sole focus shifts a bit from
40k (WFB is safe because of polish players' huge focus on
ETC tournaments) and we have some people taking a break it's not because
40k is considered inferior or bad in any way - we just try out various products to make our tabletop days a bit more diverse just like buying various board games to try new stuff rather than move
en masse over to another one and forget about the previous one.
Hell, we even have new
40k players lately and
GW's products sell like hot cake at my
FLGS, especially now after Dwarfs and Wood Elves when people start new armies just because they found the new models awesome(and both those armies look fantastic on table).
