I have seen many modern boards with elaborate designs of the TwinTip board ends. Some have wavy designs, some have more pronounced symmetrical horn looking ends.
Can any one explain the signiffcance of these? Is this just a marketing gimmick or do these different shapes actually have some merit over the flat / slightly curved ends?
I think the critical aspect of the tip shape is whether it is more rounded or more rectangular in its shape. Rounded ends (like a mako) are better in chop and waves and rectangular ends are better and load and pop and upwind.

IMHO
The important thing about the tip is that the board will stand up when leaned against a wall so needs to be overall flat on the tips. The wobbles in and out do nothing in particular as far as I have tested. The outline, the flex the twist, the rocker. The specific area where the board flexes all make a huge difference and are really important.

Not sure you are talking about tip shape Plummet, the rounded ends on the Mako for example are more to do with the outline than the tip shape.
^Agreed.
As Adrian has said, overall I find tip shape to make little difference as it's the outline or curves of the length of the rail that really make a big difference in board handling (also the rocker). A more curvy board will be easier rail to rail and nicer through chop, whilst a straighter board will be easier upwind, faster and better popping. Really though that is a huge generalisation, many aspects go into board design, it's all a balancing act. If you manage to balance all aspects properly to achieve a design that does what you want from a board, then it's a good board.

Its more a combination of outline and how it runs into the corner of the board and then the corner itself can have a some influence on pop and turning, the rest, after that doesnt matter

Although I get what you are saying, I think you are mixing up terms a bit as the outline and tip actually form the "corner" as you put it. The "corner" only has some influence on the ride due to the shape of the outline and tip of the board, thus to talk about the "corner" as it's own entity and having an effect on the overall ride of a board makes little sense to me.
the nobile 2hd has been the only over emphasised shaped board that performed for me, but only in big carved transitions, the alkita boards have some radical tip steps and fin placements and fin positions, the more you ride them the better you and the board perform, just think about switching and the alkitas do it, they've got relatively small fins but somehow grip better, they are really stiff but ride smooth as silk in choppy conditions, shame he hasn't sorted the spray

It prety simple realy Rowdy even you should be able to grasp simple board dynamics

Awesome. He showed you Rowdy. Face.
This is the board that sparked my curiosity ... The Naish Motion. I think it has the most elaborate twin-tip end of all board curently on the market.

They have been around for ages.
Check out the Naish Thorn from 2007
nobody has mentioned spray deflection and tip shape
Tip shape is just the ends of the board... the outline (or curve of the rail) and rocker play the biggest parts in spray deflection, however I will agree that a slightly rounded tip shape does help a little.
