Tabletop fantasy and science fiction war games firm Games Workshop expects pre-tax profits in the current financial year will be ahead of expectations.The company, best known for its Warhammer and Warhammer 40k products, as well as for a gaming system based on JRR Tolkien's "Lord of the Rings", said that gross margins have been strong since the last trading update at the end of November.The group has continued to deliver cost savings and cash generation remains so healthy the company has more money than it knows what to do with, so it intends to whack up its interim dividend from 4.95p last year to 20p this time round. ---jh
