Yes, you can still spin at speed, which - I've never had much luck seeing pokemon to try and catch from the tube anyway, so no big difference in my book.

This week I managed to catch two Magmars, (in a rare example of the tracker working - see shadow, keep walking, loose shadow, turn around, shadow comes back, take only available side road, Magmar! And another one!) and then promptly hatched one about 15 minutes later! I also hatched an Aerodactyl, and walked my Cubone enough to evolve a Marowak, so that's three new additions to my Pokedex!
