England coach Peter Moores believes the game will benefit enormously from the explosion of interest in Twenty20 cricket.
Moores' side will compete for huge cash sums after a series of £10million winner-take-all challenge matches against Sir Allen Stanford's 'All-Star' side was announced on Wednesday.
Moores, speaking as the '20/20 for 20' series was launched at Lord's, told Sky Sports News: "It is exciting for the game of cricket."
He continued: "The fact it is getting people talking will spill out across the world. This is a different format with different pressures and brings a different audience. That is good for the game.
"But Test cricket is here to stay, it is the foundation of all we see."
Texan billionaire Stanford has promised more than £50million over five years for the games to be held in Antigua.
England's players will be handed £500,000 if they win the first match on November 1 with a further £500,000 being paid to the other members of the squad and £500,000 for coaching staff.
England augmented their squad with some specialist - and not centrally-contracted - players for the World Twenty20 last autumn and Moores insists the best players for the job will again be picked.
He added: "We need 11 players for the game and enough to cover for injuries, 14-15 or 15 would be the normal size squad.
"I don't think there will be pressure from centrally-contracted players. We will pick the best players whether they are centrally-contracted or not."
