Hmm..I do love me a good Rumour..though nothing is confirmed..this guy does seem responsible but honestly i think that this is very likely to be fake..we will just have to wait to March to find out if this information  is true:

A Quote from Ultimacanti:

Now, for my huge show of faith I will give you the other 4 pokemon designs that will be shown in March (already told you the eevee one). AfterI post this, I will probably logout until mid-March (hopefully with new info) when more people will believe me after the reveal.

Pokemon:

• Small dolphin with clown face paint (no clown nose) and a striped hoop around its belly. (summary says it gets 1 evo) (This is a Picture of a Dolphin)
•  A bird that looks very similar to a plover, mostly white body with black stripes, forming something like a hashtag on both sides of the body. Also stripe across eyes. (summary says 2 evos) (This is a picture of a Plover)
• A fluffball with only small legs and a nose sticking out of it (cannot see eyes). This is the new rodent, but the animal it is based on is neither associated with fluff or Europe. (summary says 1 evo) (This is a picture of a Fluffball)
• A small kangaroo with a battery-pouch and two hammer-like hands. Its tail is spiraled (no obvious lightning marks on its body) (summary says 2 evos) (This is a Picture of a Small Kangaroo)

I would say that this guy is pretty reliable..i heard that he leaked Snivy and Mudkip's names before they were revealed..so i think this could be true
