That website also has information on all possible Far Future plants.

Possible Returning:

Chomper

Starfruit (Miles is gonna love this array of returning plants. Starfruity on the other hand...)

Marigold

Possible New:

Citron - Shoots powerful balls of plasma. (What do these powerful plasma balls do? No idea.)

E.M.Peach - Explodes and destroys an area of machines (No idea what machines are, but they sound like a powerful obstacle)

Infi-nut - Weaker than Wall-nut, but regains health.

Laser Bean (Accidental Leak, PopCap video) - Fires a Laser Beam in a whole row

Magnifying Grass (Accidental Leak, PopCap book) - Fires powerful light beams that cost sun (I was right!)

Tile Turnip - Creates a singular Power Tile when planted (What are Power Tiles? No idea.)

We can't confirm these, but if this is true, it seems, no, it is not at night, so no mushrooms. It also seems that according to the same website, Zomboss is back. Hmmm....
