Something told me that they would bring Christmas skins for this time of year, and indeed they did. It was the perfect time to bring back the discarded ice level, but maybe another time.
For now, some ideas for future patches would be:
-Improve some animations for plants and zombies (Cherry Bomb explodes as if it were PVZ 2, and the dolphin zombie is able to jump over a Tall-Nut with Pumpkin despite having planted it one space after the edge of the pool).
-Add the Zombatar.
-Add new unlockable content through achievements (if the player has all the achievements, the unlockable content will be automatically unlocked).
-Have the option to change the color of the cursors for both players (on Gamepad/controller mode).
-Add the option to change houses as in the old console version.
I sincerely hope that this game is not just an HD remaster of the first game, but a beautiful and wonderful tribute to itself, to the series as a whole, and to the fans who have come to appreciate this incredible franchise.
