I understand that the equinoxes (that's a wierd plural) are different. However, if you look at a star chart you'll find that in the current epoch the solstices occur at the points where the ecliptic crosses the galactic equator: the summer one in Taurus (6 hours RA), the winter in Sagittarius (18 hours RA).
In thinking about this I realize that the situation will change with time. With precession the location of the solstice will shift away from the coincidence with the galactic plane over time. Perhaps the woo woos are correct in stating that it will be the closest to that point in 2012. However, it's already pretty darn close to that spot now. Neat coincidence, signifying nothing.
