(Updates with Almunia news conference)

BRUSSELS, April 28 (Reuters) - The European Union's new members that have freely floated their currencies seem to be able to sustain their fast economic growth better than those with rigid currency regimes, EU forecasts showed on Monday.
The "free-floaters" -- Poland, Slovakia and the Czech Republic -- are also doing a better job in keeping inflation in check than Estonia, Latvia and Lithuania, which have pegged their currencies to the euro.
Controlling inflation is a key requirement for EU newcomers seeking to join the euro zone. Slovakia is expected to adopt the euro next year, but other countries are likely to follow suit well after 2010.
In a twice-yearly forecast issued on Monday, the European Commission cut its growth projection for Poland, the biggest EU newcomer, to 5.3 percent in 2008 from 5.6 percent predicted in November last year. In 2009 Poland is seen growing 5.0 percent.
"The effects of financial turmoil are foreseen to remain limited due to ample liquidity in the market and strong demand for housing supported by rising employment and wages," the Commission said of Poland.
The European Union executive cut its 2008 growth forecast for the Czech Republic to 4.7 percent -- still relatively strong in view of the global credit crunch -- from 5.0 percent and saw 5.0 percent growth in 2009.
The Commission's growth forecast for the euro zone in 2008 was lowered to 1.7 percent from 2.2 percent seen in November.
Slovakia is also expected to grow strongly. But Hungary's expansion is forecast to be weak, which analysts have said results from the government having let its budget deficit balloon to the highest level in the EU in recent years.
For Latvia, the Commission slashed its 2008 forecast to 3.8 percent from 7.2 percent and projected growth at 2.5 percent in 2009.
Estonia's and Lithuania's growth forecasts have also been cut and the three Baltic countries' inflation rates are expected to soar, confirming analysts' forecasts of a slowdown following economic overheating.
"Because in these economies investment in the housing sector was very, very high, the overheating of the economy was more clear than in other cases and the tightening of credit conditions is taking its toll," EU Monetary Affairs Commissioner Joaquin Almunia told a news conference.
SMALLER BUDGET DEFICITS
Latvia's annual inflation is forecast to increase to 15.8 percent this year from 10.1 percent in 2007, before falling to 8.5 percent in 2009.
Poland's inflation is seen increasing to 4.3 percent in 2008 from 2.6 percent in 2007 and declining to 3.4 percent next year.
Many analysts have said those EU newcomers with fixed exchange rates, which cannot fight inflation by increasing interest rates independently, often have insufficiently tight fiscal policies to keep prices in check.
The Latvian economy grew by double digits in 2005-07 thanks mainly to a credit boom that boosted private consumption and real estate investment. But inflation is the highest in the EU at 16.8 percent in March.
Its current account deficit has widened to about 20 percent of GDP, one of the biggest in the world.
Estonia and Lithuania experienced similar problems, though to a lesser extent.
The Commission also forecast that with exceptions including Hungary, most EU newcomers not yet in the euro zone would have a budget deficit below 3 percent of GDP, meeting one criterion for joining the euro.
Another exception is Romania, whose deficit is forecast to grow to 3.7 percent of GDP in 2009 from 2.5 percent estimated for 2007. Hungary's deficit is seen at 3.6 percent of GDP in 2009, higher than the 3.2 percent agreed with the EU.
Almunia said that in June the Commission would propose ending its budget discipline procedure against Poland after the country brought its deficit below 3 percent of GDP. (Editing by Dale Hudson/Ian Jones)
