The perspective of different niches to work in the next 5-10 years?

[Aquarius]

I would like to hear the opinion of the forum members on the most promising areas for commercial galleries, beginning work in a new time of troubles. Talking about Russia, and for the most part - about Moscow.

In my opinion, more or less accessible for the uninitiated, and have some commercial potential in the following areas:

1) Collectible art artists of the second and third series, has made a name for at least 10-15 years.

2) the Art of young artists with the chance to enter the TOP for 5-10-15 years, and potentially demand by collectors.

3) the Unique DPI of different quality and prices, demand for interior decoration (may have artistic value, as a bonus).

4) Mass and replicable work - posters, prints, pictures - again, used for interior decoration - budget, but using mass demand (a La posters from IKEA).

I deliberately leave out of consideration the direction that is almost impossible to raise without connections, experience and money, like working with artists of the first row or Antiques.

If your friends asked you for advice about niches for new gallery - what would you have advised them of the listed items, or suggested to pay attention to some other areas?
